have you tried St. John's Wort? -- I do believe that a person is not supposed to take it with SSRIs, tho. And light therapy helps SAD folks a lot too.

Also, since you're a CAD person, it might be useful for you to try a couple weeks off each major category of carbs--no grains for two or three weeks, no sugar for two or three weeks, no potatoes for two or three weeks...and see if that makes any difference. If when you read that, any one of that list made you panic to read and think about giving up--that's the one.

I used to have a touch of SAD as well as being exhausted every night of my life (which someone could have interpreted as depression, tho I knew it was not)...and a Protein Power/Atkins approach has cured me. For me, I do think the grains are poisonous to my system, even moreso than pure sugar. (Can't ever remember bingeing on the sugar jar or hard candy, either, come to think of it.) It's a food sensitivity issue as much as a carb issue.

HTH! Hang in there--April isn't far away at all.
