Hi thanks for your question.
Increased blood glucose
level is common cause for nocturia(urination during night).Dry palate
and need to take a lot of water is also symptoms of increased blood sugar.But since your these symptoms are associated with urgency and burning sensation which are symptoms of urinary tract infection
(UTI).I think most probably your blood glucose level has increased and addationally you have UTI.I would suggest you to consult your treating physician who may get your blood glucose and urine examination done to rule out or confirm increased blood glucose level and UTI and manage accordingly.
Hope this answers your question.
