It has been recognized by many natural health professionals that a person with a healthy body and with a healthy nervous system dreams every night... and usually several times a night.
The ability to dream at night is a very good gauge to determine if the body has an adequate supply of nutrients for the nervous system.
No one knows the optimum amount of nervine herbs but from those who report to me, it appears that a true difference is not noticed unless the amount is increased until one is dreaming every night and remembering that dream for about 20 minutes upon awakening.
Dreams happen only in the 4th level of sleep called REM (Rapid Eye Movement). Nightmares are in the 5th level or a deeper level of sleep and still indicate a deficiency.
It is illegal for me to make a suggestion on the amount to take, but personally I started with the amount on the bottle and after a week, I hadn't dreamed nightly I took 1 extra capsule a day per week.
Week 1 - 6 a day
Week 2 - 7 a day
Week 3 - 8 a day .... etc.
When dreaming, I then backed down but stayed on the recommended amount until I became symptom free.
