Currently on the right combo from my Dr that's been helping me a lot for my BPD and mood disorder. 20mg lexapro, 200mg Lamictal and 1200mg Trileptal. I have gotten used to the lethargy and my 40mg vyvanse helps but the one side effect that is really bothering me is the constant twitching and ticks I get in my face. Especially eye squints and nostril flair. The same thing happened to me years ago when I was on Depakote. My doctor said it's a very rare side effect but a very low dose of Benztropine mesylate may help. He wants me to start with .25mg at night. I already don't like being on the meds I am because they affect neurotransmitters and after reading up about this new medication I see it also affects neurotransmitters especially acetylcholine which I don't know much about unlike dopamine and serotonin like my other medication. The twitching and tics are annoying but I would rather deal with them then take something else that could potentially cause long-term side effects. Any thoughts? Anyone use this before? Sides?
