"i&#039;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&#039;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&#039;t think they&#039;re addictive in my case, rather if i don&#039;t take them i&#039;m back where i started. insomnia was a problem i suffered from for years, not just a temporary deal."
