Saw Psych Doc today.

This is about my diabetes and bipolar. I saw my psych this morning, he noticed how high my mood was by how i was acting, especially with talking veey fast. I agreed with him. This bit now is to do with my diabetes. He noticed how dry my lips were, which they are, and so dry that my lips are cracking and are very sore. He said to drink more, i have noticed that i am drinking more but going by my testing, my levels are not high. Now do i contact the nurse at the surgery?

Thank you for replying.
My mouth is ok and not dry. It's just my lips.
