Last night was my first time taking efforex. I took the pill at 8:00 p.m. and at 3:30 a.m. I was wide awake. I was nausea and had a stomach ache. I tossed and turned until 5:00 a.m. and then I throw up. I finally fell asleep for 1/2 an hour and when I woke up, I was sweating. I feel weird today. I see myself down and isloated from everyone. I called my doctor and asked about the side effects and he told me it must of been something I ate. He told me not to take today and but to take it tomorrow. One thing for sure is that my brain is wide awake.
