... are gone. I tried both Kava Kava and GABA. While years ago I got great relief from Kava Kava, this time around nothing. The GABA reaction was immediate and it made my anxiety much worse. I quit taking it immediately. Will the effect of L-tryptophan diminish over time, thus causing me to increase my dosage (1000 mg/3xday)? Should I consider 5-HTP as well, switching it out with the L-Tryptophan after a few weeks and then reverting back? Can both be taken together? How much seratonin adding is too much? How do you know if your body is getting too much seratonin and causing damage? After getting burned on the GABA and the Kava Kava I wanted to research well before making any more purchases
