Diovan Valsartan, Generic Version, Diovan, Dizziness, Drugs

There seems to be similar increases in nausea and dosage size of Diovan. Dosage has gone in two years from 40 to 80 and now 160. I am pursuing the idea that the nausea is caused by gastroparesis, which is slow emptying of the stomach, and there is some indication on websites that Diovan can indeed cause gastroparesis. I am now backing off the Diovan dosage slowly, by chopping pills and taking the 80 pill plus about 20 or 30's worth 12 hours later. As the pill is coated a bit, I wonder at what rate the exposed, chopped pill piece dispenses itself.
I had an endoscopy a few days ago and it was mostly negative, no cancer, no esophageal damage, no Barrett's, a little redness in the stomach lining which the surgeon is testing for H. pylori.
I have lost about 14 lbs due to being careful with all the nausea, and it is time to work outside on my vegetable crops, so I hope to get the BP down the right way and get rid of most or all of the Diovan.
The nausea happens about 12 hours after eating.
Anybody else having nausea?
