I took 2 dulcolax tablets (the recommended dosage at 5 mg each) at 10:00 pm. I had abdominal pain and a restless night. I awoke at 6:30 am to use the bathroom and experienced severe abdominal cramping followed by nausea and loss of consciousness. I bruised my head in the first fall. I fell unconscious once more while trying to get to water. Thankfully, my husband heard me and came to help at that point. I still could not stand. I became very hot and broke into a sweat. Then, I had severe, explosive diahreah and was unable to leave the bathroom for 30 minutes. When I felt save enough to lie back down, the abdominal cramping continued and muscle cramping in my right leg began. It's been 3.5. hours since the fainting spells, and I still cannot get too far from the toilet.
