I'm sorry your immune system is a health factor. I figured since my children's pediatrician told me there are no side effects with it aside from drowziness, that the suppliment was fine.

If a person has an irregular sleeping pattern to start with, keeping an active diet, and a nightly routine that encourages calm restfulness will only encourage a healthy sleeping pattern. Also, a healthy diet will help with sleep too (limiting sugary and high in caffein items).

The root of the sleep irregularity should still be checked out, and if you're not sleeping for more than two days, insomnia should be looked into. Sometimes it's comorbid with a mental disorder (ie - Bipolar disorder or OCD).. In those cases getting the disorder under control can limit irregular sleep patterns. In more unidentifiable cases it may be necessary to go to a sleep research center to get to the cause of the sleep issues.
