Do you use any sleep aids?

Melatonin has been linked to headache, dizziness, nausea, stomach cramps, drowsiness, confusion or disorientation, irritability and mild anxiety, depression and tremors, as well as abnormally low blood pressure. It can also interact with common medications and trigger allergies. If you use melatonin, have you had any side effects?

Studies have found that while using melatonin can be helpful in inducing sleep if used correctly -- taking it at least two hours before bed -- but the actual benefit is small. "When adults took melatonin, it decreased the amount of time it took them to fall asleep by four to eight minutes," Dr. Cora Collette Breuner, a professor in the department of pediatrics at Seattle Children's Hospital at the University of Washington, told CNN last March. If you use melatonin, do you find it works?
