I woke up feeling dizzy. Checked o2 saturation. Drank water. Ate cinnamon life cereal, my Cpap is working ok, my apnea events was one per hour for the two hours it says I slept. Been horribly dehydrated. Used liquid IV and drank 32 oz of bottled water with it added. I THINK I am feeling better now after two hours! I also started my period after just over 3 months without it. Cramps! Still a normal amount of bleeding for Day 1.
