Hi.
Thanks for your query and an elucidate history.
If it is just going to toilet 3 times in the morning , nothing much to worry.
But you say there are undigested vegetables and
tiredness , lack of enthusiasm, you need a treatment.
The present treatment you mentioned is one of the best regimens, you can slowly withdraw then in doses and duration.
Well, if your Doctors have diagnosed this as a case of an
IBS , there is no specific treatment.
Yet to add ::
You can add
creon or pancreatic supplements with food / avoid strictly all the foods and beverages that these cause or enhance such problems.
Instant decision as to have an absolutely stress-free life is a must and changing the lifestyle can alone help you better than the medicines,
