I have really terrible insomnia too. Then I tried my friends Pregabalin, and oh boy. Never had such a restful sleep.
It is a bit habit forming, but if you keep it to just before bedtime it's a wonderful sleep aid, and much less risky than Xanax.
It's not without its risks of course, and some people are better with it than others, but might be worth asking your doctor about. They prescribe it for almost anything where I'm from.
That's fair, I have also heard that effect happens to some people. I should also mention when I used it for sleep I tried to use it very sparingly, and never try to exceed much higher than 150mg for sleep. Otherwise higher doses get too groovy for me haha
