I Started Taking Furmosmide About 2 Weeks Ago. I Take

I started taking Furmosmide about 2 weeks ago. I take 1 pill in the morning to help my swollen feet. This is the only different medication I have been taking. For the last several days, shortly after supper I develop a very sick stomach, until I go to bed. Would this water pill be causing the sick stomach? I am going to try stopping it for a few days (not sure how long it takes to dissipate from your system) and see if this makes a difference?
