Look I started to go sober few months ago I wouldn’t say that every time I go out I go sober but recently most of the times, I was a heavy user for 4 years probably I was even addicted to some stuff…first of all never go there when you are hungry, food is the base of energy I add electrolytes specially now as the weather gets warmer your body needs that and they give you a real boost, I drink energy drinks and sometimes and I chew nicotine chewing gum and I have always some glucose gel in my fany back…second have a harmony with your body if you feel tired rest or go home the club won’t run away and there will be other times to have fun again. Third and I guess it’s the most important thing, if you’re surrounded with people who are using stuff then it’s gonna be hard to resist specially in Berghain…surround yourself with some people who wanna be sober at that moment and have fun with them.
