About 15-20 minutes after the nightly dosage of GABA, I feel a shortness of breath, almost a struggle to inhale. The feeling only lasts about twenty seconds. I thought it would have subsided after repeated nightly consumption, but it has not decreased at all. I have been taking around 2-3g which is less than the "recommended" 5g dosage. Just wondering if anybody has any thoughts on this or if anyone has the same experience.
