That makes perfect sense to me. A lot of people feel pretty peppy on Sudafed, or anything containing ephedra (ma huang). Taking one, for me, means not sleeping for 48 hours. It's probably not a great treatment long-term, sadly, because like any stimulant it will deplete your adrenal system and leave your baseline level of energy even lower, in theory. Glad you had a good day.
