I've just recently started temping and know that I should take my temp at the same time every day. I set my alarm for 6.30 as that's when I get up for work. I thought it would be really easy - the alarm would go off and then I'd take my temp. Well, yesterday I woke up at 4.50, so took it at that time, then turned around and went back to sleep again (didn't actually get out of bed). The same happened today, but at 3.30 am. So it looks like I'm not taking my temp at the same time every day. What should I do? Take it when I wake up at weird hours or try and fall back to sleep and take it when the alarm goes off at 6.30?
