I try very hard not to forget to drink one glass of wine per day. Usually it is at night, when I come back home, together with my Lithium, marijuana chocolate for sleep, Elavil for sleep, and supplements. This routine makes it a little more pleasant to be dealing with so many pills.

Alcohol in moderation, and what moderate, optimum level of consumption is depends on whom you ask - the health authorities in the US say that it is one glass of wine per day for a woman and 2 for a man, but health authorities of Quebec, France, and the Netherlands (these are examples I have) advise more. So, we can conclude that if you can and like it, you should drink at least one glass per day on most days of the week, which is what I am doing. It confers protection against dementia, and I care about since both my grandmothers (both were non-drinkers) had dementia later in life. It also confers cardiovascular benefits.

Opinions differ, so my close friend who is a psychiatrist advocates against combining benzos with alcohol, but is OK with taking alcohol with lithium, and I can say that in my experience, there is no interaction between Lithium and wine.

Since you have been combining Lithium with wine without issues, and since you talk about one glass of wine, which answers Confused's question (meaning - yes, you CAN stop after one) unless your glass is the size shown in the comic Venus posted, I do not see any problem - you have already proven that you can handle moderate drinking to your benefit.
