I travel for a living. I was diagnosed Type 2 back in May of 2009. I have been handling it very well since then. I do have a mechanical problem with my supplies. I must travel by car in the southern part of the USA including Florida and I am not sure if the heat is affecting my test strips. I just had a bout with my meter and strips while on the road away from home. First, I got several different error messages. I called the company and I reset the meter. Next I got radiacally different blood test readings, anywhere from 110 to 145 all within a time period of less than 3 minutes. The company is sending me out some new test strips. Have any of you had to deal with this? I have the Accucheck Aviva Meter and strips. Also, do you have any suggestions for traveling by car with such equipment? Thank you.
