A lot of people get an initial onset of an anxiety attack from GABA supplementation and afterwords feeling great.
wiserd, GABA is not a nootropic. Also, how did you determine you were allergic to GABA supplements?
Luv2increase- It's interesting to hear that the symptoms go away after time, though it's strange that they occur in the first place since GABAergic drugs are supposed to be sedatives.
The idea was to use GABA to increase deep sleep and improve my sleep structure (I was also testing the stuff to give to my girlfriend who has fibromyalgia.)
The people on here with little or no scientific background attempting to self diagnose their maladies sometimes crack me up.
I have an undergrad in biotech, actually, though I work as a web developer. It's not exactly a degree in neuroscience, but I've done a fair bit of reading on that topic in my free time as well. I had severe anxiety and itchy palms from taking GABA, and read that some people are allergic to GABA on various weightlifting forums which had the most info on the topic (since GABAergic drugs are used to increase hGH production.) I only took one or two caps. Since a putative sedative caused a reaction that was very un-sedative like and other GABAergic drugs (like theanine) don't have this effect on me and other people were claiming to have had allergic reactions to GABA it seemed a reasonable explanation for what I experienced.
Of course, I'd certainly welcome a different mechanistic explanation for what happened if you can offer one.
