OK, definitely go see your doctor right now.

Even if your blood sugar level is OK presently and no signs of ketoacidosis yet, this could be around the corner.
Undertaking any kind of big diet change (even a so-called "good" one like going vegan!) as an insulin-dependent diabetic is something you really need to be in touch with your physician about, to make sure you have good advice on how to do it and monitoring how your body responds closely.
Prevention is better than cure eh
General point: This is part of why internet medical advice sucks - people giving advice have to rely on the broad strokes of what the OP wishes to share, which may not be complete, and may mislead - bluntly put, garbage in, garbage out.
