Yep....I"m just over 17 weeks...and I'm supposed to be onsite at work for 2-4 hours and then come home and work the rest - that way I can lay down and use the laptop. WHen I DO that...it's great! But last week I worked there for 8-9 hours and then yesterday I was there 13 (It's budgeting time and getting ready for month end)...and I'm exhausted. I think all I did was drive thru fast food ...eat on the way home and then get my shower and sleep.
Yup, that's pretty normal. Healing takes energy, plus being laid up for a while means you've lost stamina. Keep eating good nutritious food, sleeping plenty, and doing as much as you feel up to, and your energy will come back.
