I'm waiting for FRQSC too. I really hope the results will be out before mid-May.
And you're not alone with insomnia. I wake up at night thinking about the results. In fact, I spend all week (last week) waiting and not being able to do anything productive!
Maybe it depends of the university but at OttawaU, You can accept OGS and then cancel it if you got SSHRC. You should ask your school if it's a possibility.
