I recently started taking 5htp. I wanted to get off benzos (which I had been taking at a very low dose for two years. I had all but tapered when I started the 5htp. So after a week, I added GABA, Glutamine and Selenium. I started waking with very high blood pressure (when it is usually 120 over 80 or lower) and nausea, dizziness, lethargy and a feeling of pressure in my head as well as headaches. The GABA pill I take is a lozenge with a combo of GABA, Glycine, Tyrosine and Taurine. I stopped all the supplements for three days, then went back to one 50 mg capsule of 5htp. My blood pressure shot back up and all the other symptoms returned. I may have taken too many of the 5htp that first week, but I felt great and was starting to sleep really well. Not I am not sure what it going on. Any ideas?
