<p>There is really no reason why it would help with insomnia, unless the cause of the sleeping problems was pain, fever, or inflammation. There are not any ingredients in regular advil which are known to cause drowsiness in most people, though if you read on side effects of almost any drug, it could be listed as one,as well as nausea. But drowsiness would not be an expected effect at normal doses.</p>
<p>I have taken Advil for years for back pain, and now long term use of this medication has been associated with increased incidence of heart attack and stroke. As my mother has had many strokes (and her father did as well), I have switched over to naproxen, which has not been associated with the same cardiovascular risks.</p>
