Sleepy - Hot weather

I started on iron pills yesterday for 'mild anemia.' They're supposed to give me more energy, willing to try them but yesterday and today I'm actually more tired. Maybe I'm just letting myself give in to being tired now? Anyway, it has been over 100 degrees lately, and that could be a big part of it as well. I'm also up and down several times each night but not for any specific reason... I just wake up after a few hours and then go back to sleep after another hour.
