I had the same surgery 2 weeks ago. I'm a little tired and weak, but sleeping well. I find myself making spelling and math errors and not wanting to do anything extra. I'm taking vitamins and trying to be gentle on myself. I have a lot of pain in my left breast. I take 2 advil every 6 hours and ice it. Do you have pain? Meletonin helps. You may want to get one called Mid-Nite which is a short dos if you need just a few more hours of sleep. I pray you get your strength back.
