[ Other - General Health Care ] Open Question : Lately I have been having sleeping problems... I cant go to bed before 1 in the morning...?

When I lay down it takes me a while to fall asleep and I wake up quite a bit when i finally do fall asleep.. and I when I wake up in the morning I'm still really tired and fall back asleep until 1 or 2 in the afternoon. And When i eat... I will take a couple of bites and get full and when i'm really hungry and eat a full meal i feel really nauseous afterwards... Also when I wake up in the morning or from my naps i feel like i'm going to puke... or have that taste. And i know i'm not pregnant.. I just got my birth control shot... and had a test then.. and this has been happening for about two weeks now what could be the problem? I have never had an eating disorder... lol i like to cook and eat lol... but any ways help?
