So, I’ve been taking Berberine to help cure my cravings, specifically sugar. I used Zhou brand, I picked up at my local Whole Foods. The night I tried it, I was fine. Then I used it for a few days, about 30 minutes before my big meals. That same evening I could not sleep because I started having very violent coughing attacks and had a lot of post nasal drip. At first, I thought it was just seasonal or environmental allergies. But I continued to take berberine and continued to have these episodes and about a week later, I thought…maybe it’s the berberine?

So, I decided to take a few weeks off and my cough and post nasal drip stopped. Then I decided to get a new brand, Horbaach, and that same evening when I had one dose at dinner, the violent coughs and post nasal drip return.

I tried googling and seeing if this has happened to anyone and can’t find anything. Is my body rejecting berberine? I’m curious to know why the post nasal drip and violent coughs happen. I have not found anything saying those are common symptoms. Any insight or similar experiences?

Thanks!
