NPR,
Don't give up! I am 8 days post surgery and I am just now feeling better. Remember to keep hydrated. I used a medicine cup to keep sipping Water. My stomach pain was worsened by takingmedicine. Try a few tablespoon on applesauce or yogurt before you take your medicine. You may need to take a daily acid reducer, as well.
I used a heating pad constantly and slept on my side. My doctor also prescribed an anxiety pill (Lorazepram) for me. It helped me to sleep. I also took hot baths to relax.
I think you will feel better when you eat more. That made my weakness and back pain subside.
Best of luck!
