I just was bragging on how good I was getting along and now I have fallen on my face

(thank heavens, not literally.) A couple of nights ago I had a severe attack of diarrhea and the very next day my symptoms have returned. Not so much worse on the pain and burning, but the numbness and awkwardness in my hands is back up to at least 60-70%. Now, I was also being weaned off the neurontin which was at 900 mg per day. I am now down to 300 mg at bedtime. So my question is.........

did the episode of diarrhea deplete the levels of Alphalipoic Acid, or should I consider that I need to go back up on the neurontin? I was doing so well and this is like getting kicked in the stomach......makes me want to vomit!!

Or cry or both. Was also thinking about doubling the dose of the ALA to 1200mg for a couple of days to see if that changes anything. Just want to hear what you all think..........
