I applaud your honesty and posting about your concerns...

Checking in with your physician would be a very good idea. I've no idea if you are on other meds, but there may be some kind of reaction happening to you.
Because something is sold OTC does not mean it is harmless. Most of them when used in moderation won't cause problems. Used as you describe can, though...

If you are finding it helps you then your physician can prescribe something mild to ease any of your symptoms. It's far safer than self-medicating.
