I know the feeling...I wake up with tremors and a racing heart if I fall asleep for short periods of time. Have you seen a doctor about it?

Try thid method for a nap.
Sleep on your back keeping your self straight.Take 8 breath (with nostrils)
Chane the position to right side and take 16 breaths.
Now turn to left side and take 32 breaths.
Breathing should be normal and feom the nose.Do this before you go for a nap/
There is no harm in trying. If you are takig nap after meals, sit in vajrasan.Fold you leg from knees and sit on them for 5 to 10 minutes. This is a yoga posture. You can search VAJRASAN in yoga website.
