Ordered that last night, regular capsules and extract. Will experiment and report back.
Here is the update:
day 1 I took 100mg extract + 400mg herb (in one capsule) in AM and PM. Felt stimulation with some warmth in the face (this is how I react to stimulants). Handled stressful work day better, maybe more motivation, but no improvement in night time impulse control.
day 2 I took extract+herb in PM only and immediately got a headache that only partially responded to tylenol. I was noticeably tired and depressed the entire day and no improvement in night time impulse control.
day 3 I took 400mg herb capsule in AM (no extract thus presumably weaker) and immediately got a headache too. Improved functioning at work though despite the headache (took Alive for that and it's a bit duller). Who knows what will happen tonight, but I'm not very hopeful.
looks like headache is a pretty common side effect:
Taken internally, side effects could include headache, upset stomach, nausea, dizziness and drowsiness.

To be fair, i'm taking this on top of my usual stack and i respond to some other stimulants with headache too (adrafinil).
Anyone with any better solutions?
