I WOKE UP, TOTALLY ALERT, AFTER ONLY 2 HOURS OF SLEEP. THERE WAS NO GOING BACK TO SLEEP. I WAS ALSO HAVING WHAT FELT LIKE A HOT FLASH BUT COOLED DOWN O Fri, 25 May 2007 00:24:06 -0400 http://www.medications.com/effect/view/12898?item=216 I had the exact same thing happen to me last night. It is strange because I took the same drug, same dosage, about 2 weeks ago for 6 days, and had no side effects. I felt completely normal except for a slight metallic taste. But I kept one pill in case http://www.medications.com/effect/view/12898?item=216
