Is unisom habit forming

Unisom, which contains diphenhydramine as its active ingredient, is an over-the-counter sleep aid. While it is not considered habit-forming in the same way that some prescription sleep medications are, regular use can lead to psychological dependence or tolerance, where users feel they need it to sleep. Additionally, prolonged use may result in side effects, such as grogginess or impaired cognitive function. It's always best to consult a healthcare professional for guidance on sleep issues.
