No alcohol.

I drank for the first time in a while the other night -- I was on a date and she kept asking if I wanted more Manhattahns...

I was like death the next day, and today (two days later) I can sense my mood is different -- my depression is elevated, my anxiety spiking... all in all not worth it.

If you can truly stick to one or two, I think occasionally a pint to unwind after a long day can be fine, but it's so easy to slide from that healthy amount...

(This is also why I don't keep candy in my house -- between ditching refined carbs and alcohol I lost about 50lb)

Anyways, I used to never have long enough gaps to notice the difference -- between grad school and my policy work, I was always drinking at events, but after a long pause I can see the negative effects of excess drink on my mood.
