Have been an ibs sufferer for many years and have just had a severe 6 day bout of constipation. (Which took a massive amount of laxatives to resolve). I already take one and a half Movicol sachets per day and 25mg Amitriptyline. I have just been given a new drug called Constella 290mg but forgot to ask if I should take this with the Movicol. Can anyone also tell me if I can take this with peppermint oil capsules?
