Do they actually work for you?
I tried one a few years ago while undergoing chemo while also attending classes but it didn't do diddly squat to keep me from dozing off.
Tried another one earlier tonight thinking it might work better this time but all it did was give me a caffeine headache. Far from bringing me back to 100% as they advertise. It did help keep me from nodding off of a little but did zilch alertness wise.
