Yeah, I know finding the right cocktail combination can take a long time, but that is something that most people with bipolar have to deal with. Please hang on!
If your doctor feels that he/she has run out of options I would suggest that you find another. There are many combinations of drugs out there that he/she can try.
I know nothing about Symbayax but I wanted to offer my support and hope that it starts to kick in for you.
Keep us posted on how you're doing.
