well, i realize now that i did go a little overboard with the ephedra (aka hydroxycut). i was boarderline of taking too much, and i know that if i ever do take it again just to finish the 2/3 of the bottle left over, i'm definitely gonna take less. less than 1/2 of the max dose i was taking. 99.99% sure i'll probably never buy another supplement other than creatine and glutamine. while i was taking hydroxycut i did cut out all cardio, and i had lost all sight of what i had lost, which was all the benefits of being healthy. the clarity of mind, and the refreshing feeling of waking up in the morning, necessity to sleep less, and the feeling that you are physically capable of anything (like running a mile at a snap of a finger) was all gone. i'm back on track with my cardio, and from just doing the cardio again for a short amount of time (and without the ephedra), i'm up to capacity again.
