Dear Uditguru, You have not mentioned your age here. But the sugars you mentioned here are unlikely to increase frequency of urination. hence you need to rule out two conditions primarily. One is urinary tract infection and the other is benign prostrate hypertrophy. The later one is common if you are more than 50 years. The lethargy might likely be because of the sleep disturbance due to urination. another rare causes include excess calcium in the body; hence get your calcium profile done. Tendency to drink excess fluid; hence just see if it has any reason. If not, then try to restrict fluid intake during evening hours. If you look at your fasting sugar, for a person with new onset diabetes, it is high. Hence you should make changes in the night medications for diabetes to normalise fasting sugar and that might also make wonders. Take care.
