I'm on MJ and as soon as I went from 2.5 mg to 5 mg I became constipated. Without being too graphic, the issue is not about retaining water in my bowel. I'm drinking loads and also taking Movicol so I am loose but still almost no bowel movements. I obviously need a motility stimulant and will be straight off to the pharmacy tomorrow when it re-opens. If anyone else has had this problem and resolved it please tell! Do you take something like bisacodyl regularly? Have you found anything other than gut stimulants that helps?
