I've been on Zoloft (sertraline) 150mg for years now and my anxiety is under control but the last few days I can't sleep and im not anxious I done get it, what coul?

Anxiety ; insomnia. Have you added any new medicines, supplements, or recreational drugs -- or stopped any of the same? Do you drink alcohol? Any changes to your pre-sleep routine? Anything worrisome on your mind? How is your mood, and your energy? These are some things i'd ask in working with you -- your own psychiatrist will want to know the same. Cognitive behavioral therapy can help w/insomnia also.
