My degree in medicine involves a lot of chemistry and I think I'm destroying my body.

I don't do cocaine or heroin as there's too much risk.

I have however been taking various combinations of speedballs in a chemistry sense. I have been doing Co-codamonster, where I take 2-3 Co-codamol with monster, at first it was just a nice buzz and then I increased the dosage on both the painkiller and caffiene. The codeine C4, which you may guess from the name. Sometimes I'll smoke 2-3 cigars for the nicotine buzz pairing it some prescription benzodiazepines which puts me in a weird awake sleep state.

I'm becoming increasingly more irritable when I don't hit.

I know I have to quit or cut down but I'm scared.

Summer is when people traditionally go on vacation
Wouldn't going on vacation for 3-4 weeks without access to drugs help you quit? I haven't been able to quit weed, but when I went to Japan, or when I spent time on the opposite coast with my parents I didn't have access to it which gave me weeks of sobriety
