What's your deadline? I was given just a month to turn around my corrections, get the thesis hard bound, and resubmit it. Would have taken half that time in practice, but various academics were away/out-of-the-country due to Easter.
Personally I wanted to get my corrections out of the way as quickly as possible, not least so I could graduate next month. How many corrections do you have to do? Have you made any start? Do some of them look more appealing than others, for example easy typos to fix? If so start with those and that might get you into the swing of things.
I also found listening to podcasts while doing the corrections took my mind off the tedium :p
