Congrats! Posting and reading here has helped me through the tough times too.
As for the sleep - everyone is different but my sleep has improved almost every day since about day 5... still get the weird dreams but they're not so bad lately (not sure if that is because they are less weird or I'm just getting used to them!)
i have even managed a few nights of sleeping straight through 6 or 7 hours - it truly is a wonderful thing to wake from! :-)
