Hello onebeed,

Welcome to the NeuroTalk Support Groups!

I see you've found the PN forum so I'm sure that the members there will be able to offer you information and support.

If you need to find specific information about the medications you've been taking then you can always do a forum search. You can search just the PN forum or you can search forum wide.

A temporary measure for helping with the reflux at night is to sleep with the top of your bed raised. That's a very unpleasant side effect you're having. I know there are many members here who have taken or are taking Gabapentin, so hopefully you'll find some information about that from then.

Regarding your B12 levels. Did the doctor say what it was?
Doctors I've come in contact with are still are working on antiquated measurements unfortunately so it would be interesting to know what your level is now.

all the best.
