I used to drink heavily and then a couple of years ago I scaled way back. It's amazing how many friends you lose once you don't want to drink all the time. Even friends we still have we don't see as often as we used to. There is a couple we've been friends with for years who whenever we go out with them or go over to their house they're always having a couple of drinks, then they open a bottle of wine and sometimes a second. We've gotten better about politely refusing after two drinks, but sometimes we fail at it. I notice when I have more than two drinks I don't sleep as well and I'll feel a little off the next day even when I'm not hungover. Unfortunately, this has caused us to come up with excuses to not be able to see them as often when they invite us over. It's not the lifestyle we want anymore and while they've taken notice and have been more conscientious about it, they still sometimes pressure us a bit to have more with them.
