Need. Need more information to try to provide a meaningful answer. What specific vitamins, herbals and supplements do you take and at what doses? Are you taking any medications? What is your age? Are you obese or normal weight? Do you drink alcohol, if so how much? Do you eat heavy meals before going to bed? Do you have any medical conditions? Have you had a sleep study?
