I have high levels of glutamate and dopamine in the brain and my doctor recommended theanine to reduce it. However, theanine interferes with my sleep (even small amounts taken in the morning) -- I don't go into deep sleep all night. Does anyone know of something that reduces glutamate in the brain? I asked my doctor about taurine and he said it doesn't work anywhere near as well as theanine. I'm also wondering if I could take something with the theanine to prevent the sleep problem. It says on the bottle that it increases alpha waves (maybe those are the ones that help you feel alert), so maybe something that decreases alpha waves or increases the deep sleep waves (Delta?).
