Maybe it was the drug doing the talking, but you sure wouldn't have said or done those things if you were in control. You can outdrink anybody. Being able to hold your liquor sounds like a good thing, but it isn't. People who can drink a lot without feeling the effects are at risk for alcoholism. Watch out if it takes more of any drug to get the same high.
Drug abuse can lead to other risky behavior.
A lot of risky behavior may indicate a problem. You forgot last night. If you don't remember all or any part of the evening, it's time to get a grip on something other than the bottle. You've changed friends. You don't want to talk about it.
