Thanks, Misssy2 for your response. You brought up some good points. There always is that anticipation when it comes to trying a new medication and the anxiety associated with that. Luckily, my reaction to Gabapentin is not as extreme anymore. The rapid heart beat issue is no longer there. I did accidentally take it during the day (at work) since I had to call my pdoc to ask her whether she recommends it at night or day. I didn't feel terribly tired at work from it, but I felt a little 'different.' She told me switch to Gabapentin at night.

It's working out well now. It doesn't make me tired (it's definitely the Seroquel that knocks me out), but I can still see why the Gabapentin is best taken at night. I'm starting to feel the anti-anxiety effect and notice I don't need Klonopin as frequent as before, although the Klonopin is still needed.

I'm glad this is actually helping a little bit. I was skeptical at first, but my pdoc told me so many people do well with it. I think some of my skepticism was because Gabapentin was never FDA approved for Bipolar Disorder or Anxiety, so I often do not know how to feel about off-label meds. I'm glad I stuck with it and wonder in the future if it ever will be approved for mental health conditions.
