Hello marionalma,
you might have narcolepsy or hypersomnia just guessing, you will get to know what it is your problem when you consult a sleep doctor. But I am posting some helpful self care tips for you.
Go to bed at a set time each night and get up at the same time each morning.
Try to exercise 20 to 30 minutes a day. Daily exercise often helps people sleep, although a workout soon before bedtime may interfere with sleep.
For maximum benefit, try to get your exercise about 4 to 5 hours before going to bed.
Avoid drinks that contain caffeine, which acts as a stimulant and keeps people awake. Sources of caffeine include chocolate, coffee, soft drinks, non-herbal teas, diet drugs, and some pain relievers. Smokers tend to sleep very lightly and often wake up in the early morning due to nicotine withdrawal. Alcohol robs people of deep sleep and rapid eye movement sleep(rem) sleep and keeps them in the lighter stages of sleep.
A warm bath, reading, or another relaxing routine can make it easier to fall sleep. Sleep until sunlight.
Maintain a comfortable temperature in the bedroom. Extreme temperatures may disrupt sleep or prevent you from falling asleep.
If you have trouble falling asleep night after night, or if you always feel tired the next day, then you may have a hypersomnia and should see a physician.
Good luck,
marvin.
