... I take 1mg of Xanax 4 times a day. I didn't take my morning dose on Wednesday because I was running low. I was fine. But around 10:30am I don't remember nothing till almost noon. It seems I had had a seizure. Lucky my husband was home. He called an ambulance. I came too and he told me what had happened. I have went without taking it before and nothing happened. What could have caused it this time? The hospital did there test and the only thing they could come up with was from my medicine me not taking it. I am on day 3 and I am still so sore and have bumps and bruises showing up all on my right side. I apparently hit the coffee table on my way down. Has this happened to anybody else? The seizure lasted almost 15-20mins. I am scared now to be left alone with my 2 year old.
