insomnia
"I've  been using Kirkland brand doxylamine succinate now for many years. I take only 1/2 a 25mg pill and find it works just as well as a full pill, without making me drowsy the next morning. Here and there I find myself without a pill if I'm out of town and forget them or run out, and what happens is I just go back to the same I Sonia I had for ten years prior to taking these. Therefore I don't think they're addictive in my case, rather if I don't take them I'm back where I started. Insomnia was a problem I suffered from for years, not just a temporary deal."
