Keisha was wondering whether to have a sleep study.
“I asked my doctor to give me something for my insomnia,” she wrote, “but he wants me to have a sleep study first. He thinks I might have sleep apnea. I don’t think I do. I don’t snore (as far as I know). I wake up a lot at night but I’m not short of breath or gasping for air.
