I hope that you will get the pump!
This does not sound like a good way to test your basal rates – nor does it seem like a good way to control your blood sugar. If you ever go more than 4 hours without an injection, you could be facing serious DKA. Are you doing injections every 2 hours or how often? If you ever oversleep and don’t get up to give an injection, you could be in serious trouble. I do not think that this is a good idea and would advise taking your basal insulin until you actually start on the pump.
The best way to test your basal rates is after you have a pump and you can do fasting tests that are described in the book that Mike recommended, Pumping Insulin (it’s really the best!). Given that a pump gives you a very, very small dose of insulin every 5-10 minutes, it is impossible to replicate this with injections.
Keep us posted if you get a pump! Please, please take care of yourself (i.e. take your basal insulin until then)!!
