I work in a controlled environment (73+/-6F and 35 +/-15%RH) and I keep the temp in my home at about 70F. I take Lantus twice a day, once when I first get up and again right before bed. My morning fasting readings for the last month average 85. My lunch/exercise readings are around 80 and bedtime readings tend to be higher based on dinner but stay in the 100-120 zone.

I think if you are worried about temp influences the easiest answer would be to split your dosage into two injections to minimize any possible influence.
