Thanks, cool info, Aly! I might eventually shift to a configuration more like what you were considering in the menthol thread. I haven't had any luck with any variations of the amino acid blend so far. I'll keep trying, though.

I've tried:
4g L-glutamine, 2g L-aspartic acid, 400mg L-theanine
4g L-glutamine, 2g L-aspartic acid, 1 bag green tea (my oh my does this taste nasty!)

So far, neither combo I've tried has resulted in any increase in lucidity or dream quality. I do feel slightly amped and/or aware when trying to fall back asleep but it hasn't really led anywhere interesting. I'll probably try it with 200mg L-theanine next and then start considering some bigger tweaks. I love the idea of working through the glutamateric system, so I hope this will work out.
