I can't respond specifically to SAD, but between knowing a lot of psych, and my own experience, I'll share what I know. I recently had a very huge anxiety attack to the point where I had to be taken out of the anxious situation and then I the anxiety turned to depression. I was first put on klonopin(sp) just because the extremity of the anxiety, that's only to be used in such cases, it can be addicting. Then I was started on lexipro, which took a little while to kick in. Actually, experiences, it takes much more than 2 weeks for most meds to work. I think mine might have taken 6 weeks to months before I started feeling a difference, sometimes it can take 3 months. Lexipro is more for anxiety, side effects it's had on me included increasing tiredness and that seriously increased my appetite. It mainly increases seratonin, the neurotransmitter which controls mood/emotions and dreams...my dreams actually have been more vivid as a result too.
Between the weight and tiredness, my psychiatrist added wellbutrin to the equation and I think with time she wants me to go more ot that than the lexipro. Wellbutrin is supposed to increase more dopamine, which relates to learning and energy and increases norephephrane which well controls mainly arousal, my psychiatrsit made a joke b/c I had just studied all the neurotransmitters yes people like this one becuase it makes sex more enjoyable. Haha. So it's giving me more energy, and I was told it's supposed to make my appetite less, that's odd that it increased yours, Ma.
In terms of getting help for it...I too would recommend finding a good therapist, and it could take time, you wanna find one you're comfortable with. I've seen two years ago, and neither was particularly helpful, one I actually disliked. Now I have a really good one, she's worked with people like me a lot and she loves Broadway and the Yankees so sometimes I'll spend half the sessions talking about Broadway with her, it just makes me happy and more comfortable. Once you find a therapist, usually they're associated with a psychiatrist. The psychiatrist controls your medication. What would then happen is you'd see the psychiatrist once a month, talk mroe about medication but also how you are, and you see the therapist once a week. Again, you may find medication is unnecessary from the therapy. Good luck!
And anyone can PM me any questions they have, I won't be seeing my psychiatrist for like another 6 weeks, but I can totally write down the questions and be sure to ask her if anyone would like.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
