Man unrecognisable after swapping £750 weekend binges for the gym
A man who ballooned to 15st thanks to £750 weekend drug and drink sessions with his mates went sober, and has ended up ripped. Nathan Knight first began to experiment with drugs and alcohol aged 15 when he attended house parties with older friends.
The now 27-year-old said he quickly fell into £750 weekend binges where he would drink up to 15 pints a night, take 'any drugs he could get his hands on' and gamble. In his early 20s he tried to remain in shape by going to the gym but his health was hampered by his partying and he found himself using up to 3.5 grams of ketamine a day at his worst.
The sales advisor, who lived with his mum, claims this went on for 18 months and she would often get so worried about him she would call an ambulance. Nathan tried to go sober in 2022 but said it only lasted seven months before a spontaneous pub trip escalated into a four-day bender.
But after meeting his partner in July 2024, Nathan admitted he needed to change in order for the relationship to work and to stop him from ending up 'dead or in prison'. When he found himself drinking beers at the breakfast table and acting 'erratic' on a holiday in Marbella with his new partner's family, this was his final straw and he quit in October 2024.
Now 20 months sober, Nathan credits meeting his new partner for 'saving his life'. He has also now lost three stone dropping from 15st 2lbs to 12st 2lbs by swapping his boozy weekend binges to five sessions at the gym a week.
Nathan, from Farnham, Surrey, said: "I was a binge drinker and weekend offender and because I had nothing going on with my life I would go out and ruin it even more. It would be all weekend and I wouldn't want to stop. I would wake up hungover and continue drinking as I wouldn't want to get that anxiety [that comes after drinking].
"At this age you don't have money so I would be taking any drugs I could get my hands on. I was a social butterfly and when I was drinking, I would be very outgoing and try to be funny with everyone and I'd take whatever I was given whether this was ketamine or cocaine.
"I was just trying to get away from my actual real life, I didn't want to be sober. At the time I would be getting £750 a week and I would spend it all on the weekend. This would go on alcohol, drugs and gambling.
"In lockdown I was 22 and I would be sitting in my room. I'd be doing it [ketamine] sober every day. This went on for a year-and-a-half and I was living with my mum at the time. There would be times when she'd ring the ambulance because she thought I was dying but I'd be in a K-hole.
"I was doing 3.5 grams a day of ketamine for a period. Meeting my new partner [made me change], within a month of knowing her I went out to Marbella with her family and I was acting erratic.
"I would wake up in the morning and would be drinking beer while they were all having their breakfast. I was ashamed and disgusted [that I was drinking beer while they were having their morning coffee]. I was ashamed of what I looked like, I can't even look back at the photos as I knew I looked ill.
"I knew I needed to make a change to save this relationship, I knew then it was time. I had an overwhelming epiphany and I said I was never drinking [or doing drugs] again."
During his drug binges Nathan claims he wouldn't eat but would then scoff a whole large Domino's pizza and a 'couple-sized' Chinese takeaway in 24 hours. Nathan now opts for a high-protein diet and has a green smoothie every day for breakfast.
Alongside his gym sessions he now also plays football twice a week and says daily tasks such as walking up the stairs feels easier after going sober and losing weight. Nathan said: "I've always had a love for the gym and exercise but I never had that routine or the consistency because I would go out on these binges.
"I never saw any real changes in my body until I went sober 20 months ago. Now when I look back, I think 'how did I let myself get like that?'. Since I've stopped drinking alcohol not only has my anxiety diminished, I never had more money, I've never been doing better at work and personal relationships are better.
"It's completely changed my life. I look back at the person I was 20 months ago and I know I would have ended up dead or would have gone to prison."
Nathan is now sharing his sobriety journey to show others you can make a recovery and turn your life around. He says one thing that has helped him stay sober is not restricting himself from attending social events, instead opting for alcohol-free drinks.
Nathan said: "You just need to take one day at a time. The days will accumulate fast and before you know it you have made a huge difference in your life and there's a way out and drugs mask the reality of actual life. It's only when you take a step away from it and you're not drinking or taking drugs that you realise the effect it has had on you and the people around you as well.
"I think this [not throwing myself into social situations] is why I relapsed when I went sober for seven months. [Now] I still go to social events and I socialise and be around people that are drinking and I'm fine with it."
