There are several good articles online that explain about phlebotomies. I picked this one to post from Verywellhealth.com Towards the middle of the article there’s a new heading for “Side Effects of Phlebotomy”. It explains the benefit of saline IV after the treatment replacing the loss of fluid.

You had quite a few blood draws in a short period to get your numbers down. The volume change can make you feel pretty sluggish. So maybe next time ask about having an IV and see if it makes a difference for you.

You’re not alone in having issues with the smoke from the fires. I can’t imagine how awful it is in Canada to have that level of impact here in the US. I don’t usually have a problems when there are ‘poor air quality’ alerts but both my husband and I were finding it hard to keep up at our usual pace with our daily walks and working outside. That had to really be difficult for you. Hopefully the fires get under control soon for the forests, citizens and wildlife of Canada…and the US.
