high blood pressure
"My doc just put me on this stuff last week, the first afternoon I took it, I was just so spaced out, and walking around in a fog, I hated it. I thought I would take it before bed, so the fog would at lest be while I slept. WRONG! Took it around 10:00 PM, went to bed at about 11:30, fell asleep ok, THEN... woke up at 1:00 AM, with pounding heart, and mild chest pain. Was awake until 5:00 AM, slept maybe an hour, then had to get up for my day. 
didn't take it the next night, and decided to take the next day in the afternoon. Well, here I am, feeling like garbage, and reading all the bad reviews. Not going to take anymore of it. Thanks to all who shared."
