Irritable Bowel Syndrome Treatment

I have IBS (Irritable Bowel Syndrome). I just recently started taking an over the counter medication for it. I drink a cup of coffee a day,sometimes none at all. My friend says that I should cut out coffee completely. I wouldn’t miss it, but I was wondering if that was necessary? It doesn’t say anything about caffeine consumption on the box or the bottle of the medication.

I’m 5′4 155lbs. I’m overweight. I plan on flushing my system for the recommended 10days. Then starting fresh with a new diet. What is going to happen? like how much weight should i loose doing everything right and how bad are the side affects. I am currently lowering my calorie intake and next week i will be juice fasting. So i am ready for the master cleanse. And should i take probiotics after the master cleanse?

I have a preschooler and she is always getting sick from her classmates. I have been sick 4 times in the last 6 months. Do any herbal remedies actually work? I’m thinking either emergen-C or probiotics. I need something to boost my immunity. I already eat healthy, work out regularly and get plenty of sleep.
