I all, I know how miserable it can be to have IBS.
I thought I would let you know I have cured my IBS twice now. No doctors, no prescriptions and no over the counter remedies.
But ....it takes time and can be quite expensive.
My method is simply to take two Actimel Pots after my weetabix every morning. On the two occasions I've done this I have cured my IBS but it will take (in my case) four months. Yup, that's a long time!
When you think of what IBS is, spasms of your stomach, you need to make it as easy as possible for food to move through your intestines and the way this happens is by making sure you have plenty of good gut bacteria to break down your food before.
I'm really confident in my method, I know I'll always be susceptible to IBS, but life is easily manageable when you have the solution.
I've seen some posts where people suffer anxiety and depression and the fear of going out in case they get caught short needing the toilet. I totally understand this, I was there for YEARS! This will go away almost straight away - without being too OTT with the information, the day you wake up and have a regular bowl movement without stress, you'll be out the front door and going all over the place, confidently knowing, feeling good inside that you don't need the toilet.
I am now going to toilet once a day - stomach is completely fine with 3 meals a day, I no longer think "what time am I going to need the toilet?" - The answer is always "Tomorrow" :-)
Good luck!
