I gave up smoking 18 months ago and have been slightly constipated ever since. Its better than it was but I still find it difficult to go every day and if I don't go my stomach gets hard and I get terrible cramps. I have found that drinking a small amount of prune juice everyday helps a bit but if I drink too much then I get diahorrea. I am healthy 31 year old female. I am not overweight and I eat a very healthy diet including lots of fruit and vegetables. I have tried taking digestive enzymes, linseed oil, califig, fiber supplements. None of it has particularly helped and I am sick of worring about when I am going to be able to "go" and how long it is going to take.

Perhaps the smoking in some way had a very negative effect on my digestive system? I have read online that others have experienced these symptoms too. Please - any advice you can give would be very helpful
