I don't take anything at all. Sometimes if I've had a nap and can't wake up fully from it before a workout I have just a tiny bit of sugar...not enough to spike my blood sugar to cause an insulin rush...about 1/5th of a teaspoon. If you're training hard 5 days a week it's not surprising that you feel tired and probably need a little break...say a week off. Then try a 4 day a week program and see how that works...that's my schedule and I take a week or 2 off every 13 weeks or when needed. You have to use a periodization type of training cycle to avoid breaking down...take it easy when you are tired and don't rush it until you are fully recovered from it...then you can give it a push for say 4-6 weeks.
