How are you with potatoes, Megan? They're an extremely good carb source. Or turnips, carrots or parsnip. Yams? I'm just trying to think of good carb sources, but don't know how low starch these are (except potatoe which is part of Dr. Ebringer's original idea of low starch - but we're all different, yes?).
Also, now that you have the referral, you have the right to get the name and phone number of the clinic the appointment will be at. Which means, you can call and be put on a cancellations list to get in even earlier! Although January is way better than March. What a gift it must have been when you found that out!
Warm hugs,
