So i've toked a few times as a last resort to sleep. Its done the trick, however I notice I  have vivid nightmares of past trauma every time I do . Has anyone else experienced this? Xanax  worked in the past, without this unpleasant effect but doctors don't want to give  that anymore. I don't mean for me specifically, just in general. As in, there's no point to ask because they won't give it to you. What works for you to catch some Z's?
