Cleared for surgery! When do they call? (St Joe's)

Got the good news from the surgeon almost 2 weeks ago and haven't heard back from them. Do they call just before your 2/3 week window to take optifast or do you get some notice?  I mentioned I'd like to do it in May due to prior work and other commitments, so I'm wondering if that has caused them not to call yet. 

I did leave a message and no surprise, I haven't heard back from them. 

Anyone have an idea how they do it at St Joes (Hamilton)? 

Thanks! 

Congrats! I'm through Thunder Bay, but i've seen some post in Facebook groups for St. Joes that they get their call and have to start their opti right away for surgery when they get their call. Hope you get yours soon! Take Care :)

Yikes!  That's a little nuts they do that. Fingers crossed that doesn't happen, I've gave then plenty of time to schedule. (Hopefully)

Thanks for the input!  Is this Facebook group for anyone? If so, could you share the link?
