I can relate to not feeling well after surgery. My surgery date was August 12, 2013 and just about 3 -4 months ago I started feeling normal again with more energy. I felt tired all the time, my heart rate was going crazy and on top of all that my gastroparesis kicked in and my stomach had stopped on me. I found this out about 3 wks after surgery in the ER for like the 5th time they did a CT scan. Since being on the beta blocker and building up my muscle I feel so much better.
