I took 2 Dulcolax tablets Wednesday night at about 11:30 pm. Abdominal pain woke me up at about 4:30 am Thursday morning, and I had to rush to the toilet. It was only 5 mins after I returned to bed that I had to return to the toilet. I had little pain during the day yesterday, but I used the toilet about 5 more times during the day. Today I have not gone to the toilet, but last night and presently I'm experiencing stomach pain, lower abdominal cramps and I feel nauseous.
