@DEERBLOOD @GolfCartLady @Jean_Philippe_Micheaux @MuscleOrc1221 That's fair. Up your b-vitamins and seriously look at L-theanine. Gives you milder stimulation than caffeine. It's what's in green tea. You could actually switch to that for a while and see if it helps. Less jittery and more of a smooth focus with a bit of energy.
