Topiramate
"I have been on Topamax twice now. I don’t typically write reviews for medications, in fact, I never have. 

I took Topamax at 100mg along with Lamicital 100mg for Bipolar, I slowly titrated off my meds because my doctor and I thought I possibly could function without them. Bad idea. I spiralled into a terrible manic episode where I was sleeping less than 2 hours a night, even on high doses of Ambien and Lunesta.

I finally was put back on Topamax 200mg this time and it has saved my life. I feel better than ever. Initially I was put back on 100 mg and I felt better, began sleeping 3-4 hours a night within a week. Went up to 200 mg and within 2 days was sleeping 9 hours a night and my racing thoughts and anxiety had completely gone away"
