I wonder how many of you who have trouble sleeping or staying asleep, are taking allergy medications. I went through a pretty bad spell of insomnia a couple of years ago. My wife eventually traced it back to the 24 hour Allegra that I had been taking. I looked up patient complaints and symptoms and 80% of people who were taking it listed insomnia as a side effect. I stopped taking it and within a week was back to my normal sleep pattern.
