No, no, no, antidepressants don't work that way. Just as it took you some time for the celexa to start working, so would a higher dose. Also know that serotonin levels are not the problem with mental illness and aren't what celexa is really doing -- it's not making any more serotonin than your body makes naturally, what it is doing is altering the natural way your body uses it. The reason anxiety is triggered in many anxiety sufferers when using alcohol or other drugs is it disorients us to use them -- it's why we like them -- but when you're an anxiety sufferer, disorientation feels like what it feels like when you're really anxious so it triggers the same feelings. Doesn't happen with everyone, but it does happen a lot.
Well, it is a little concerning you want to medicate your way out of side effects of drinking. I'm wondering if it wouldn't be a wiser decision to drink less (or no) alcohol. That's such a vicious trap. Any medication changes should always be supervised by your doctor. Serotonin is involved with anxiety and depression. And many drink to mask feeling and emotion. It's such a common thread in addiction. It can very well all be intertwined. Do you, by the way, see a therapist? That could be very helpful. Here to help any time I can. good luck
