I've been on MJ since October, but the constipation issue hasn't eased, in fact has got worse - it's been just over a week since my last poo. I'm on 5mg, which is working (albeit slowly, only 1.5st since I started). I have been taking physillium husk tablets, but they don't seem to be doing anything. I rdrimk an average of 2l of a day. Any suggestions?
