YY to 'you just get on with it'. Also:
An hour or so of TV in the morning for DC so you can doze on sofa.
A helpful DH who does his 'share' and doing shifts: I do bedtime-12am (when DH gets home from work), DH does 12am-4am, then I do 4am onwards. Leeway is important; for instance I am up feeding a teething DD2 as DH's attempts to settle her were futile.
Extended term BFing - this isn't relevant to you, but I'm BFing longer than I necessary want to, as I know that sometimes, the only thing that will settle DD2 quickly is a boob in the mouth 
Antidepressants
I was diagnosed with PND, which I am convinced is due to sleep deprivation as I noticed a clear pattern between DD having a particularly bad night and my mood the next day. ADs do seem to take the edge off.
And most important of all:
Early nights, I'm often in bed by 8.30/9pm, I find it makes disturbed sleep easier if you have a couple of hours sleep behind you (luckily
DD2 rarely wakes before 12am, and usually 'sleeps through' until waking up for the day at 4am).
I'm glad your DD is on the mend, it can really throw you when a 'good sleeper' stops sleeping well.
