I cannot say it won't harm you, everyones different. The dzine is a methyl...so you know about support supp's for the liver ??
Most posters here do not respect these kinds of questions, so the replies have not been so nice, call it tough love.
My recommendation is this, when I party socially I tend to have alot, not binge like but much more than a lite night. It's your B-day so first I think a light night won't happen and even if it did your risk to fun % is way off so its not even worth drinking
Best case - has no impact
Moderate case - hangover, feel like crap can't do 100% effort at gym
Worst case - liver failure
So I've tried to reason with first then I put it in not so technical terms now is the scare tactic.
I've been into see my friend at the hospital. Seen him lose all gains and then some. Tube sticking out his nose, IV's, what a frekin mess.
