Ryan,
Give it time, I feel confident this is going to help you, I never had the other meds, but the Lamictal has done me well.
Sounds like your doc is titrating properly, in fact that are the dosages I started with, went up to 200mg or 300mg (can't remember) but I am down to 150mg's now, with pdoc's approval, we agreed if things start changing I will go back up with his supervision, and if need be anything else he deem's helpful.
Just wish he'd let me address my ADD besides the Bipolar, my former pdoc said after 3 yrs. and things worked out for my mild Bipolar, she'd try small dose of a med for ADD.
Personally I think I am more ADD, than Bipolar, especially when I look back at what a horrible, distractable student as a kid.
Amazing how in college (while taking diet pills/stimulant) I did terrific, even made honours twice, kind of is a sign, I need ADD meds., eh? Oh well, till my pdoc realizes it, I'll go with whats working for the Bipolar part of me

Lots of luck with this and do not lose faith, okay?

Sincerely,

DE
