I started gabapentin 3 weeks ago for unbelieveable nerve irritation in my brain/neck and almost total insomnia-(plus jerking, twitching/neuro hell was hoping it would help with). It is helping- I can at least breath during the day ( I was holding my breath all day long it was so bad before)- Problem is now I have constipation/hemoroid issues. I never have been constipated. I'm pretty toxic now and don' t want this to add to it. Any suggestions welcome- thanks.
