Internal bleeding after they discharged me home following a minor laparoscopic surgery. Long story short I lost so much blood my blood count went from low 40s to 23. The hospital transfuse at 22. So they gave me no donor blood. They fixed the bleeding and again sent me home.

Found out right away that I felt fine idling, but was out of breath climbing hills or stairs.

Tried training a few days later. Lmao. Garmin was very VERY disappointed in me.

Did a 1/2 Iron 5 weeks after that incident. It was the toughest race ever. So that's what it's like when you enter an event as a couch potato.

Was not back to normal for over 2 months. That was WITH taking daily iron/folate/C/B complex pill.
