I've got a few months to toy around.
PEA - I've used it without any MAOIs, I found the effects to be short-lasting and gave me an emotional roller coaster (feeling very up and happy, and then very pooped and depressed 40 minutres afterwards)
Tyrosine- I've used it and enjoyed it, I found it useful when I lacked sleep or was exhausted. It seemed like a toned-down version of PEA.
I've used both cdp-choline and alpha-gpc. I first used cdp-choline along with piracetam and later switched to alpha-gpc as I found it to be a much more effective choline source.
I think for my purposes, adrafinil or methylphenidate would work best.
