Nobody should be embarrassed to use a toilet. That's what they are for! And please don't ignore the urge to go, as others have said, it just makes matters worse and can kill off the sensory nerves in your rectum which tell you to when to go. Take a book, use your mobile to listen to some music and wait. I have to say, I have to spend a lot of time in the loo even though I have had the opposite problem since a teenager (IBS), so there are noises and pongs. There's nothing I can do about that, but laugh it off. I do have experience of constipation as a result of drugs I was given to combat sickness in chemotherapy, and I had 3 prunes every morning with 'overnight oats' (oat flakes soaked in apple juice). It worked for me. I hope you are better soon.
Does anyone have a middle name?
What "back then" inconvenience would annoy today's youngsters?

Also a couple of pruned before bed!!!!
