Well if the OP rides every night and is unable to sleep every night does this mean he needs to take melatonin every night? If some one has trouble getting up in the morning does this mean they need to take coffee to wake up and go?
I'd like to say no to this because that's not the way the body is designed to go to sleep or wake up.
The body is designed to go to sleep and wake up by itself. It has it's own chemicals to go to sleep and wake up. When you introduce some thing else other than it's natural way of doing something then you are training it to rely on that substance. Substance training is in itself a patch to a problem. When you patch a problem with something you are not resolving the problem you are patching it. In doing this you expose it to other problems.
So taking a "natural" pill here, and deficiency pill there really does not solve the root of the problem.
Some people might have deficiencies in the natural chemical produced by them but that is a different type of protocol that need to be used.
Sleep deficiency can also be linked to stress which can be taken care by removing the stressful situation. http://www.k-state.edu/counseling/topic ... sleep.html
