I am thinking of trying GABA by Solgar which is pure GABA and is 500 mg. Have held off on trying it due to severe MCAS/ allergic flare-up so thought I'd ask some questions in the meantime. I've chatted with a few people about it in other threads and appreciate the feedback very much. These are my questions: 1) Have you taken GABA and if so, was it helpful, neutral or made things worse? Any side effects? 2) What dose did you take? Did you take it at night or another time of day? 3) What was your reason for trying it? 4) Is there anyone on PR who tried GABA who also has the anti GAD65 antibody? (I know this is a real long-shot but thought I'd ask!) Thanks in advance!
