Hi, I had a similar experience. I am sorry that you feel bad. You stomach good bacteria has been wiped out and it need to come back. Please eat yogurt, kiss your cat and dog, stop using antibacterial products,use soap, vinegar, ivory soap and Dawn, and dig in your garden, preferably your childhood home. Eat cheese, sauerkraut, fresh organic green, kiss your family, breath in your couch, etc. You will begin to feel better, but it takes about 3 month. There are hundreds of kinds of probiotics, and the over-the-counter ones only supply you with a few.
