I started taking a herbal product I got online called Herb a Calm. It has Valarian, Ginger, Peppermint, Calamine. No gas, bloating, pains or frequent BS's. I was back to normal but the last three nights I have been having all the symptoms again. I can't understang this at all. My anxiety is very low, lower than it's been in yrs so that not the problem. Any suggestions?
