I have been on Sertraline & Quetiapine for one year now. My Psychiatrist told me they only cause diarrhoea and I may have ibs.
Gp put me on Omeprazole and Mebeverine, but the cramping lessened, so I take Omezaprol but not the Mebeverine. Because I'd have to take it three times a day before food, but I can only eat once daily, but at night.
