I remembered that some members of the original Brain talk used GABA as part of their supplement program. My son has been making so many bathroom trips that it is having a negative impact on his life. He also had what appeared to be a panic attack the other night. He has been taking Inositol for the past year and it does help. I would like to try adding 5HTP nd GABA. I am having difficulty finding info on the GABA. What is a safe, effective dosage? My son is almost 10 and about 60 lbs when soaking wet. Also, does it need to be taken on an empty stomach? Is GABA the best supp to take or would he do better with a precursor to it? He does test borderline for pyroluria. He takes Zinc, Mg., B6, p5p, EPO, C, multi vit and melatonin. Is vit. D important? His tics are fairly minor at the moment. The anxiety is becoming more of an issue. Laurie
