3949dxer, I have been dealing with the same thing for the past year. When Valsartin was recalled my doc put on on something else that I cannot recall the name of, and it has made a big difference. On a group ride about a month or so ago I was pulling hard on a hill and was hit by an inability to get any oxygen. Was gulping for air and felt like I was suffocating.With the new stuff I don't have this problem. I will say my BP is higher than it was on Valsartin, but is not oppressively high and is right at the High-Normal level. I do believe the difference is how low Valsartin was taking my BP. Was on Valsartin for 4 years.
