Detailed answer....
Hello,
Thanks for the query.
I can understand your problem but the fact is that there is no single treatment available to cure it.This condition can be controlled with combined therapies.

Avoid chocolates,caffeine,alcohol,carbonated drinks.
Avoid honey,many fruits having fructose,fried foods etc.
In fact you have to identify foods which trigger your symptoms and then avoid them.
Consume more of soluble fibres like oat XXXXXXX barley,flesh of fruits( without skin ) 
Consume 6-8 glasses of water but either one hour before or after your meals.
You can take immodium calsules on those days when having multiple loose motions
Can take pepto bismol or PANTOPROZOLE for gas and acidity.
Can take low dose tricyclic antidepressants and antispasmodics but after consulting your doctor.
It is always best to be under the regular care of a Gastroenterlogist.
For stress reduction,you must do regular yoga,prananayama and deep breathing exercises.
These are the general measures adopted for treatment of IBS with frequent diarrhoea.

I hope it helps,however if you have any specific query or any further query,you are most welcome to ask any time.
Best of luck
thanks
