IBS- how to help naturally.

I never heard of the medicine you mentioned but I've been on all the over the counter and prescription laxatives and none of them are safe for long term use. You definitely need to see a GI specialist and find out what's causing it because some of those things can be dangerous. If you have something like what I have IBS with Acid Reflux and chronic constipation caused by the handful of pills I have to take at least 3 times a day then this is what helps, it's natural and you can use a lot less than I do if its too much. There a tea made with Senna which is a natural laxative and yes that is what's in senokot but not as much as the teas and their a pure, undiluted form. Celestial Seasons makes on called Smooth Move and I use another on called Cali Girl Dieters Tea. Since I'm only 5' as well I have to say I hope your not doing something to yourself to make you stay thin cause it has life-long consequences. The not eating all day and then eating at night is stopping your metabolism so when you do start eating your going to gain a lot of weight, fast. Trust me dear, I did everything wrong you could do except purging and I am paying for it now. A healthy eating style and moderate exercise will keep you at a normal weight and Healthy for a long, long time.
