trazadone is used for insomnia and it is an antidepressant. By itself it usually just makes you drowsy. alcohol will probably just make you even more drowsy. It's probably not good for you to drink with it. Amybe you should try it without the alcohol, and see if it helps. If not, try and get something else form the doctor. I know that alcohol will not really help you fix what is causing your nightmares. For a while I was drinking every night to keep them away and when I stopped it was worse. Sometimes I woke up screaming knowing that I was having nightmares and just couldn't remember them cuz I was drunk. anyway...I guess that's all my advice
