I'm sure you know to discuss this with your doc. It is good to be informed about your meds and it's ok to ask the doc about trying something new.
I was having severe mood swings and my antidepressant didn't help so I asked about lamictal. It is the best med I've ever taken. Bear in mind that the list of side effects are possible, not probable. I've had no rash or any effects except peace of mind.
But again, discuss with your doc.
