One of the reasons I use opiates is because i don't get a hangover, I used to drink quite a lot but the hangovers got unbearable once I hit about 25, now even 4 or 5 beers gives me a nasty headache the next day and getting drunk writes off at least two days. Morphine occasionally gives me a nasty hangover, the oxymorphone I had in new York made me really sick a couple of times but I think that was partly to do with having a low tolerance at the time and over doing it a bit.
I get bad cravings the day or two after using h and I have to up my dose of pst to counter the withdrawals from increasing my tolerance a bit, the days after a binge when you've spent too much money and have to deal with withdrawals can be pretty depressing. Blowing all my money on heroin gets me down, I get paid once a fortnight and the last week and a half I've been on the bread line from spending way to much on it. I spent the last of my money on a shot tonight and I know I'm going to hate myself for it for the rest of the week.
