I drank just about every day for something like 4 years. Usually in pretty hefty quantities.

If you feel okay with it and it's not affecting your life or work performance, then do whatever you feel like. If you feel like it's a problem, then make a change.

I realized it was becoming a serious problem and I decided to give up drinking during the work week. It has done wonders for my health (physical for sure, mental, maybe) and definitely easy on the wallet. Bottom line, just be aware of your own limits and pay attention to the signs.

:edit: been on the straight and narrow (lol) for about 10 months now.
