another question

[curious]

I know that may be better placed on the health board, but since there are a lot of people here, I thought I could get a broader range of opinions, hope that is okay.
okay, question
I know that alcohol is a depressant (downer)however, how does it affect stress levels? Does it help to lower them, make it worse, does it depend on the person? Should it NOT be drunk when a person is stressed?

I am college (Masters), and when mid-terms and finals are on, it can be major stress, so I had wondered if a glass, the night before the test (or even a couple of hours before) would help, but would it make it worse? I'd rather not pop a valium or other such type of drug.

I DO want to be responsible, so before my hubby and I have any wine, we want to know how it will affect me.
Note: I am Bipolar II, but have been stable for two years, and am allowed to regulate my meds on my own as needed.
