I was prescribed Lantus Solo Star 10 units before, bedtime. I would like to know why you need to take it at bedtime ? As without it, my morning sugar number is 82. The problem I'm having is day time and evening numbers. I take Novo Log Flex Pen before dinner, but it doesn't seem to bring my numbers down, and when I go to sleep my numbers are over 300 put always wake up with 82. Afraid of all this Insulin and getting low blood sugar while I sleep. Am on prednisone 12.5 mgs and never have been on insulin before only oral medications which am still on now.
