I have been on Invokana for 9 months. My sugars are regulated butt in the morning after I take that Invokana about 1 hour later I'm fast asleep I feel really tired real weak and I don't understand why the medication works great but it makes me feel like confused and it makes me feel tired all day does anyone else have this problem. I have not lost any weight at all on Invokana all I know is that it does help with my sugar levels which for three to four hundred for almost 8 months and now I'm down to 9110 so it does work I just don't like the feeling after when I take it in the morning. Does anyone take it at night time.
