Ugh!! Took my first pill this morning (50mg) and 2 hours later I had to leave work because I was dizzy and nauseous. Driving home I felt like horrible and wondered if I was going to have to pull over. Got home, walked through the door and proceeded to vomit and then feel asleep for 2 hours! The nausea is gone but still laying in bed. Tomorrow I will only take 1/2 or even 1/4! How long before side effects subside? I generally tolerate medicine so well. I rarely ever get the side effects on warning labels!
