Kate,sorry you are feeling so anxious.. and don't apologise please! I have had the waking early thing too but it tends to go in phases-It is horrid though, watching the clock tick round and longing to grab a few hours more sleep before you have to get up! At the moment I am sleeping ok (though still have to get up to the loo twice in the night) but I don't need much anyway-about 5- 6 hrs usually... I miss the days when I used to enjoy a lie in! Like you, I have never experienced the endorphin rush that exercise is supposed to give you either! How long have you been on Prozac-are you on hrt as well?
