I decided to try Phenergan as I was so upset with IBS. At first I only had 10mg from Dr but now have 35mg. I have never had the double dose, I still wake up with bad tummy ache about 5 and take 2 buscapan. I am not in so much pain during the day which is better. Do Shona and Rosie think this has helped and what should I do next. Please reply as I am worried about Christmas.
