@Jigsaw,
@eljefe19,
@xena - I've been struggling with severe insomnia for several months following a slow-taper off of 1 mg. lorazepam (on it for 10 years! in the middle of the night for sleep, ironically enough).
So I've been taking lots of l-theanine and several others things, mostly to no avail. And then read just recently that as
@xena said, l-theanine could be converted to glutamate. And then read in a couple of threads and Benzo buddies that perhaps it would be better to focus on getting rid of excess glutamate, instead of trying to increase GABA.
I'd also been taking lots of l-glycine which at one time did help with sleep, but then I read again just recently that it could also be converted to glutamate, so have stopped it as well.
This all led me to calcium pyruvate and resveratrol which are glutamate scavengers - and it's been amazing. I've finally started to sleep again. I got 8 hours last night - I can't remember the last time I did that. I'm also taking niacin and lots of magnesium, and 5-htp and relora. But have pretty much cut out l-theanine and GABA supps.
I also read that glutamate is the gun, and calcium is the bullet that gets it into the cells (or something like that! it doesn't sound quite right here
)- so have temporarily at least cut out my calcium supplements, though I plan to re-introduce calcium slowly, as I'm sure I need it for my bones etc.
So
@eljefe19, you might want to try the pyruvate and resveratrol. I am so surprised at how well they're working - I'd almost given up the idea of getting a good night's sleep.
