Started GABA and felt so relaxed it was amazing. I have POTS and this lowered my heartrate and I felt really good. I had a clearer head. My memory was better. My energy was better. I was only taking 425mg a day in at least 4 divided doses (taking the powder out of the capsule and putting it in a little water). I have adrenal exhaustion so suffer from hypoglycemia and it even helped with that. I read that it helps with glucose sensitivity. About 5 days in it started making me feel really sleepy. Then I started feeling really shaky. . . like it was keeping the glucose from getting into my cells. I read that it can raise insulin levels so wonder if that made the hypoglycemia worse after a few days. The hypoglycemia causes high heartrate for me. I struggle with digestion anyway and take digestive enzymes to help it but when I crash I have a really hard time with appetite and eating. It is horrible. I get so depressed with all of it. I'm waiting for my 23andme but had my kids tested and based on their results I think I have CBS expression issues. Even though my Sulfate levels are never above 800 using the strips I am extraordinarily sensitive to methylfolate and had a bad, bad crash after starting it (was on hydroxy B12 at the time). I started following Heartfixer's CBS Protocol. The GABA, Moly, and Yasko's CBS drops. I had to re-do my 23andme test because there wasn't enough DNA in my sample so I have the kids results but am waiting again for mine. I already know I am Hetero for MTHFR C677T, as are both my children. Am I bouncing from overmethylating to undermethylating?? How can I tell? So confusing trying to figure out what will, on a consistent basis, make me feel better.
