OK I know all the typical things that go into a PSK, but what about a stimulant of some sort. Either a caffeine supplement or something like ephedrine? Something to get you over the "hump" if you are completely depleted of food energy or really run down? Only to be used as a last ditch effort to get up and keep going when you feel that you cant. Stimulants can suppress appetite as well. Or on the other side do you think they would do more harm than good? Not a Doctor or a fitness expert, just a thought let me know what you think
