I did discuss the side effects with my GP was only told about the disrupted sleeping pattern. I went through Google and was quite disturbed about the other alarming effects, I took my first tablet one day ago first of one for three days. I was severely constipated and I also have a diverticulitis problem and was very worried I couldn't pass my bowels so I took a laxative and now got a very upset stomach and diarrhea. And had 3 hours sleep. I'm afraid to take another tablet without professional advice.
