Combining alcohol with lamectal, zoloft, welbutrin and klonopin

Hi everyone. I'm diagnosed with Bipolar I, and I've been stable for a little over a year. After a lot of tweaking, side effects and minor mood fluctuations, I think me and my pdoc have found the right combo of meds (for now). 150mg Lamectal, 50mg Zoloft at night and 350mg Welbutrin in the morning. I also take Klonopin as needed, up to 1 mg.

I don't want to encourage alcohol consumption among those of us with bipolar, as it can lead to some dangerous mood instability and bad decision making.

But I really want to know, in the simplest and most straight forward way possible, how the combo of my meds with alcohol damage me physically, internally. I'm well aware of the mental repercussions of a night of drinking, but I can't seem to find a concise description of the physical damage done by the combination of these medications and alcohol.

If anyone can describe, I would really appreciate it.
