Thanks for the info on ALC/ALA. I think I will try it. Does it "get along" with other supplements (b12, biotin)?

Nacho - I had heard about PN from antibiotics such as Cipro. However, I cannot attribute my problems to that - I had not taken Antibiotics for ove a year when my symptoms started (and it was amoxicillin). But I'm glad you ID'd the cause of your troubles, so you can start recovery. Thanks for the heads up.
