Brief Answer:
Thyroid

Detailed Answer:
Sorry to learn about your excessive sleepiness.

An under-active thyroid can result in such symptoms.

When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination:

CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
Calcium
HbA1c (Glycosylated Hemoglobin = your 3 month glucose average)
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine)
TSH
25 hydroxy Vitamin D

A condition called Sleep apnea can also result in similar symptoms. You will need to undergo a sleep study test to confirm this
