Complex issue: Sleep attacks are usually seen with narcolepsy, but that is unlikely at your age. Partial seizures, mini strokes, hydrocephalus, brain tumors, medications can cause your symptoms. Seek evaluation soon.
Dr. Michael Summers
Sleep Medicine 23 years experience
Multiple thoughts: 1) medication side effect 2) thyroid issues 3) insufficient sleep 4) depression (poorly controlled) 5) narcolepsy/idiopathic hypersomnolence without knowing your medical history these are the first (in no particular order) items on the differential that come to mind (assuming you had a sleep study that was negative for osa). It may a combination of many on the list as well. See your doctor.
