I usually don't post on these threads but I have been sleeping in almost every day til 12 pm, which is really weird because I am ALWAYS up between 6 and 8 am. My family has even become concerned with my new sleeping habits. I feel like something really weird is going on because I rarely sleep in past 8 am... and for the past 3 weeks it has really been hard for me to wake up before noon..... what is happening?
