diabetes, type 2
"T2.  I have been on Metformin 1000 for several years and with diet and monitoring bs levels have managed well.  Recently,  I have struggled with numbers and decided to give in to additional help in management of numbers. I started with 10 day sample of Invokana 100 and did well. Felt fine, no real issues of concern.  Even thirst and restroom visits didn't really increase. Then started the 300 10 day sample and again no real noticeable issues. Requested prescription and now, 10 days later I can barely stay awake. I have always been a 5-6 hour a day sleeper and now I am so exhausted I could easily sleep 10-12 hours a day. 
Decided to try splitting the pill to see if anything changes in my sleepiness before requesting to go back to the 100."
