I know you are meant to have 3/4 hours of sleep prior to taking your temp in the morning, but what happens if you just can't? I often wake up in the middle of the night. I don't get up, rarely need to get up for a wee in the middle of the night, but I often have restless nights where I wake often. Most times it's as simple as waking, checking the clock, turning over and nodding off again, but occasionally i'll be awake for a few minutes. It starts usually after 2 hours of sleep and it can be once every 2 hours or more than once an hour. Does it matter if it's only a little waking up like that?
