Just thought I'd throw in my 2 cents for what it's worth. I've been on Gabapentin for quite a few years. For the past few years I'm on 300mg 4 to 5 times a day. I've never experienced tremors from this med or from MS up to this point. I've never heard of tremors causing blood in the urine though. So, even though you don't have a UTI or signs or symptoms of kidney stones/infection, I'm glad you're getting the fact that you have blood in your urine checked out further. Hope the tremors are getting better for you and everything turns/ed out OK with your visit to your PCP.

Thanks everyone! I couldn't change my PCP appt. so I go on Monday.

Since I dropped down to my usual dose of gaba - 300 mg in the a.m. and 600 mg in p.m. I have started to feel so much better. I've continued drinking the Ensure and making sure I am getting all the nutrients I need as well as extra B vitamins. This has been helping quite a bit as well.

Desinie - I've been on this dose for 5 years and original started on 300 mg in the a.m. and 300 mg in the p.m. in 2003. Like you, I have never had a problem with gaba. So, I'm kind of at a loss on what to do other than the things I have been trying. It never hurts to pay closer attention to your diet.
