Well, hi at least! It's much earlier here right now, though I was up at an equivalent time to yours last night. It's very frustrating, isn't it? Came on PC (Hey! Same as you! )
Trying to remember from your posts... are you on any meds or are you seeing anyone (Pdoc, T?) I don't have anything specifically prescribed for sleep, but one thing that will work, and that's with an intermittant problem. If it's a chronic (or through a manic phase, which can certainly be long enough!), have you enquired about something to help with that?

(Btw, Toooootally agree with PT52 just above.)
