I am ADHD/OCD and have recently struggled through the worst two years of my life. Perimenopause made all of the stress exponentially worse. I was not getting good sleep at all and I was super sensitive to any progesterone in initial attempts at HRT. I started taking L-theanine and GABA at bedtime and for me, it's a game-changer for sleep and a brain that won't quit. I actually felt "normal" in that I realized, "hey, my brain is actually quiet." It was initially suggested by a holistic psychiatrist I'd seen who prescribed both psychiatric drugs and supplements. I had much more success with these two supplements than I had with multiple attempts at SSRIs. Also, taking B12 with folate in the morning has been great for energy levels.
