Detailed Answer:
Hi.
Thanks for your query and an elucidate history.
The multiple problems you have mentioned and the treatment you have been taking noted.
I would suggest a few things that may help you to get a further relief and may have a better life.
You may please continue the medicines you are already taking
-Treatment:
''STRESS'' = stress is the most important cause of IBS. Please remember and you must have observed that when you do not have stress your problem with IBS is reduced
Change of lifestyle.
I think 'may be' you are not coping with something.
Vacation outside of your area, mobiles phones to be off.
You must have noticed already that these changes help a lot.
Try to avoid anything which you are / have to do against your will and wish. Get into the hobbies which make you forget the world around you. Life comes only once, boss.

Medicines ::
You need to have a prescription of a Doctor, please discuss this with a Gastroenterologist to get a prescription few more medicines
Vit A and Vit D in therapeutic doses,
Multiviatamins ,
Probiotics,
Activated charcoal tablets.
Anxiolytics help a lot.
Adjustment of the diet and beverages- you have stop those things which you must have noted to increase your problem.

Remember the simple dictum in IBS : you have to undergo necessary investigations before you are labelled as a patient of IBS. Secondly IBS is easily treatable, controllable and within the ambit of your psychological set-up.
The moment the instigating or precipitating factors come into play the problem may re-start.

Diverticulitis needs treatment from rime to time and if not manageable by medicines, Surgery may help a lot. Try to take a second opinion of a Surgical Gastroenterologist.

I hope these small things can change the outcome very nicely, as it helps most of my patients.

Kindly feel free to ask for further if you need to.
Wishing you an early and complete recovery.
