On monday morning, I was enjoying a game of cards when suddenly felt nausea, and got very hot. the next thing I knew my boyfriend had me in his arms, I had apparently lost consciousness. he said my eyes were wide open, pupils dialated...he was about to call 911 when I suddenly grabbed his arm and looked at him. I have no recollection. After, I was cold, and shaky for hours...I still feel in a fog..I have had recent root canal problems (tooth will most likely have to come out-repeat infections), and have been taking anti-diarrhea OTC meds as I have had issues since mid-November (I was blaming it on the tooth infections)...I take one daily just to function and be able to go to work...and had taken my last antibiotic the morning it happened...could it have been a drug interaction or something else?
