GP prescribed codeine, 15mg, I started it on Thursday and haven't been to the loo properly since Friday. I know he said it could cause constipation but he didn't say what to do if it did! I've never been constipated before so didn't quite know what to expect.
I feel like I need to go but when I sit on the loo nothing happens. Have just spent an hour on the loo thinking I was going to 'go' but - nada. I feel very bloated and uncomfortable and like there's something huge there just waiting to come out. 
I eat loads of fruit and veg so no lack of fibre, I have been drinking lots of water but it hasn't helped, not sure if I should get some ex-lax or something tomorrow as I will be going out and don't want to get taken short at a bad moment! I've never used a laxative before so not sure how it all works.
I'm off to bed now but would really appreciate any advice for the morning.
