ALWAYS check for ketones if your BG is >240 mg/dl for any length of time. If you are spilling moderate or large ketones you may need as much as 100% more insulin for your correction factor since you will be very insulin resistant at that point. Best advice with large ketones is call your health care professional.View Thread
I didn't see anybody mention ketones. They should always be checked for a BG that high. If ketones are moderate or large you will need much more insulin because you will be insulin resistant. Your Novolog starts working within about 15 min., but doesn't peak for about 90 minutes. If you stack your insulin (take more before it peaks), you will undoubtedly crash at some point which starts the roller coaster effect. The heat can definitely disintegrate your insulin so that is always one of the first things to suspect. Glad you figured out what the problem was.View Thread
