I was wondering if you ladies with DCs 6 months+ have seen a thread about gradual retreat - it's called "What worked for us"? It looks pretty good, lots of successfulstories there, and I would try this myself but my DS is only 4mo, so a bit too young.
I've had a horrendous night on Saturday - caught some kind of stomach bug, so was sick half the night... Something I really needed on top of sleep deprivation!
Was down with fever yesterday, but it seems to have gone away now.
On a positive note, I managed to get DS to sleep without a dummy yesterday night! I thought it would take ages for him to fall asleep, and he would also cry, but no - only took about 15 mins. I even left the room when he was almost asleep, but still grumbling, and he drifted off himself! Then 1.5h later I heard him whimper, and was on my way to him when I thought that maybe I should wait since he wasn't really crying - and he fell back asleep again! I thought great, he's learning to re-settle himself, and was feeling quite positive after his initial 3h stretch, but then he started waking up pretty much hourly throughout the night and only boob would do... 
Boo I probably wouldn't do it myself, but I'm glad it worked for you, and so fast! Desperate times require desperate measures sometimes!
