Started taking Ultracet for severe headaches associated with Sinus infection.... felt ok with the first one last night, but today at work I am very disassociated, upset stomach, hands are shaking, dizzy, profuse sweating and unable to concentrate in "real-time". I feel disconnected from my sefla dn surroundings. I have never had these side-effects from any other medication before. And my headache is still somewhat present
