Just wondering if anyone knows anything about this medication?

I was prescribed it today (75mg/day) by my doctor for depression, insomnia and anxiety, I'm a bit worried though as my old doctor who had me on Fluoxetine said the older Tri-Cyclic antidepressants are not good and should be avoided.

I'm also concerned about the side effect list with regards to weight gain, I really DON'T want to put on any weight.

Also, Alcohol? I'm not a big drinker at all but I like to be able to go out and have a few drinks if I want to. The instructions say alcohol should be avoided but not that you absolutely can't drink at all

Another thing is its supposed to make you drowsy right? This is good in a way as I have sleeping problems but I also have to get up at 6am and I need to be able to do this and I'm worried that I'll be too zonked to get up

Does anyone have any experience of this medication they could share with me?
