Hi Bagpuss,
Don't take this the wrong way, but I think you might be wrong about being type 1, cos according to your profile page you're taking glucophage (metformin) & I think it was glimepiride or gliclazide, which are medications only used in type 2 diabetes. Not that this affects your need for help, but you might get more appropriate responses in the type 2 forum. Type 1 diabetics are totally reliant on insulin & will die within days to weeks if they stop injecting, so we have this to motivate us!
Type 2 diabetics can survive without insulin, they'll just be damaging their bodies. You might find others who've done similar to you on the forum though - hope you get some good advice that helps you.
