Jen, I'm Bekah; new here. I take 300 mg of Topomax and my p-doc also prescribes 10 mg Ambien. I am extremely resouseful with them.Meaning, I break the Ambien in half when I do take them and that's only on the occassion that I need them. I also take 140 mg Geodon, 300 mg Wellbutrin, and 20 mg Lexapro. My understanding is that Lexapro is supposed to help a person sleep also...? I stay away from OTC sleeping aids, as they leave me feeling groggy the next morning. Have you considered trying Melatonin? You can find it at Wal Mart in the Vitamin/Herb section. It's natural, and it helps! No hangover! I have such sleep issues. Rather be up all night, alone, quiet, while the rest of the world is asleep. I feel so much energy at night,knowing no one is going to call or come knocking on my door. You know what I mean? Hmmm...maybe I need to start taking my Ambien! But yeh, you can take sleeping pills on Topomax; check with p-doc 1st, tho'.
