I'm actually taking it because my damn allergies are kickin' in. I took 100mg the other night, and while I was all groggy and shit, I rolled around till 3AM.
50mg seems to do me good.
I had a patient the other night that had a mild allergic reaction; I gave her 50mg intravenously, and she was sleeping like a baby in a busy ER hallway within 15 minutes. I only wish!!
