Lumpectomy exhaustion

I had my lumpectomy on Friday, I assume everything went ok, my body aches and my boob and side are very sore and sensitive. The pain was pretty bad the first two days after and I was on my pain meds round the clock. Now I am just using regular Tylenol.

But the exhaustion I am experiencing can’t be normal…can it? I am so tired I could literally sleep all day. I am so tired that if I am woken up in the morning before I’m ready to get up, it physically hurts me to THINK or try to get out of bed. I am getting 8+ hours at night but it’s just…not enough. Today I woke up, got breakfast, then went back to sleep! And I still feel tired.
