Good afternoon

I'm desperate, I have lada diabetes and for a few months I've been getting toujeo just because I had a high basal rate.In winter I have been fine with 13 units, but when the heat arrives... as soon as I am exposed to the sun from the first minute my glucose plummets, I have to run to an air conditioner or shade and take glucose pills.The drop is real because it punctures me and it marks like the sensor.

Does it happen to anyone?I have already dropped from 13 units to 9 and it continues to happen to me.
