Lawn mower symptoms and conditions

My 4 year old Son has had diarrhea from about the last 4 weeks... we have started some tests for Celiac disease but today it only occurred to me today that he has been on Singulair for about that time frame... after all the worry and reading these other storied Im even more convinced that it maybe the Singulair..
Im just hoping that someone might read this sometime today or the next couple of days to tell me if when they come off the singulair how long did it take for the diarrhea to pass. My son had is last tablet 2 nights ago ( so he has only been off it so far for one night. But he still has the diarrhea.. should it have started to come out of his system already.

Unbelievable, I am amazed by what I am reading. I started searching for Toprol side effects tonight because I am a 43 year old woman who is usually very active in the garden this time of year. I have been taking Toprol XL since last September. I can't work in the garden more than fifteen minutes without being out of breath and dizzy. I have no desire to push my lawn mower. If you knew me, you would know there was something seriously wrong if I do not want to mow the grass. I have gained 15 lbs for no apparent reason. I can relate to just about every one on this list. I feel awful most of the time, barely able to keep my eyes open. I also get occasional charly-horses in my legs and more often in my feet. I thought those symptons were due to my weight gain. I have tried to lose some of the weight but it won't budge. I have tried vitamins and trying to get more sleep. Nothing works. I take the Toprol for episodes of severe tachycardia in a-fib. I also have an enlarged left atrial chamber with an aneurysm. Is there some other medication I can take without these side effects???? I have immediately made an appointment to see my cardiologist. thank you for having this forum, I now know what is wrong with me.
