You likely have a sleep disorder. Many sleep disorders, such as sleep apnea, can cause excessive daytime sleepiness. Other potential causes of daytime sleepiness include narcolepsy and idiopathic hypersomnia. In any case, I recommend that you see a qualified sleep provider who has expertise in evaluating and treating these conditions. From what you have described, you will likely need to undergone testing, which may include an overnight polysomnogram followed by a multiple sleep latency test.

Chronic insomnia is characterized by difficulty falling asleep, difficulty staying asleep, or awakening too early and having difficulty regaining sleep for at least several nights weekly and for three months or more in duration. Insomnia is associated with next day impairment such as tiredness, difficulty concentrating, or difficulty functioning. Insomnia is treatable either with cognitive behavior therapy or medication.

Mandibular advancing dental devices are indicated for mild sleep apnea and snoring without sleep apnea. CPAP is the initial treatment of choice for moderate to severe sleep apnea but is also effective for mild sleep apnea.

Having isolated cataplexy without any of the other symptoms of narcolepsy is exceedingly rare. I suggest that you see a neurologist or sleep specialist for further evaluation. There area very effective medications for treatment of cataplexy.
