ever since i droppped my caffiene intake my workouts have been soooo much better, no more dizziness,shaking, or weakness...does ephedra do the same thing to blood sugar?
georgie,I think caffeine also causes a boost in insulin secretion.If you take caffeine with,say,dextrose or maltodextrin and whey you might crash badly a few hours later.Happened to me many times.
i dont get it. i cant even drink a coffee pre-workout because i get fatigued and shaky(not nervous) dizzy as a mofo and almost faintes a few times while doing heavy lifting(back!) now that i stopped coffee im good to go...im really confused about glucose/insulin ect
