Seems Odd That You Are Engaging At This Time Of

Seems odd that you are engaging at this time of hour--feeling uncertain. Had a very nice Oral Surgeon remove a # ? back left abscess molar today under gen anesthesia. He seriously gave me the smoking lecture and I listened. Doing okay, but have insane insomnia...but kind of started with Menopause in Feb. I have the day off tomorrow, but feeling so strangely alert and it is not my MO. What causes this?
