I've tried hard to like Modafinil & haven't had experiences that I'd consider beneficial to my productivity
For me Fl-modafinil I didn't feel much of anything at 50-100mg
Armodafinil 150mg wrecked my sleep even if I took it first thing in the morning
& Modafinil 100-200mg would give me headaches & irratability & put me in a high stress & unpleasant state even when paired with Alpha gpc
Right now I'm testing out 50mg bromantane + 20mg 9-me-bc
I also have tesofensine, but I don't want appetite supression & don't like how long it takes to build up in the system
I also have piracetam & NSI-189 on the way
I want smooth clean focus without messing with my appetite or sleep or mood.
