Cam,
I have taken all of those medications for at least 2 months b4 my doc(s) would change them. Also have taken lithium, my thyroid gets checked about once a year because I keep thinking it has to be part of the problem. My docs talked about depakote and or tegretol but felt due to my history of "becoming toxic" that any med that builds a level may not be safe for me to take even with regular labs. I would take a MOAI but they have the same feeling about that. I have even tried a light box it is just so hard to live in limbo and see others with depression get better, good for them, hard on me.
sigh
