Are occasional night sweats (a hand full year, but not always every year) normal? some days i wake up drenched even when the room temp is the same.

Likely normal: Occasional, even drenching, sweating at night is not abnormal. Especially if you have not lost weight, you may ignore it. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
