I use to drink heavily every weekend. friday night just a few, then saturday night start at eight and finish real late. I never did any other drugs at that stage in my life apart from nicotine. I can't imagine going through those hangovers now. the pounding head, the feeling that at any moment i was going to puke and iwas almost certain that the neighbors cat had broken into my house and shat in my mouth while i was in my drunken sleep. Now i am certain there was a hell of a lot of damage being done to my brain. Now I don't drink and thankfully escaped those days relatively unscathed. As for ecstasy?(mdma and nothing else) I use once a fortnight, sometimes longer in between, one dose and there r very little discernable side effects. does this mean that mdma isn't causing any damage to my brain? I don't know for sure. If it is I can't tell from any physical symptoms
