Have used for 4 months. It caused elongation of my Uvula located at the back of my throat. When I cough I start to gag. I was visiting my doc's office, and complained about the gagging. He saw that I was using Zestril 20mg for HB pressure. He said he experienced the same thing with this drug. I went home and looked in the mirror, and sure enough it was extra long. The extra part was skinny and hanging at the back of my throat. Every time I have a large amount of saliva to swallow, or post nasal drip, it causes me to cough, gag and feel like I am choking. I stopped using it, and will wait for my Uvula to get back to normal size.
