I find myself suddenly dozing off during the day and I do not feel well-rested after sleeping at night. If the cause is sleep apnea, how will I know whether I have central sleep apnea or obstructive sleep apnea?

Most sleep apnea is obstructive. A polysomnogram test and a CBCT scan both help identify obstructive sleep apnea.
Only a sleep test (polysomnography) can determine if you have sleep apnea, and whether the subtype if obstructive or central. However, obstructive sleep apnea is far more common, so statistically you are much more likely to have this subtype.
