I guess one reason too I had tummy upset this morning it is because I ate too late last night. Yeah I ate at after 11 pm which was very late for my dinner time. This has been happening to me twice already which I shouldn't have done it. I will be more careful next time and watch the time to eat at the proper time. It's like my tummy is rumbling inside and I have been farting and I hope I have to use the bathroom soon so I will feel totally better soon. Sorry guys for sharing this in here. Please excuse my words if my gross you out.
