Hydroxyzine
"I love this medication, I've been on it for years and it does double duty for me- Both as an allergy medication and Anxiety. While I've built up a tolerance to if over the years, I love that it's non-addictive and calms my mind enough that I can relax. While it doesn't make me sleepy, it does allow me to be calm and after an episode of high anxiety, this often does lead me to sleep. While not for everyone, I personally love it."
