Ok, first, can the "cravings" on that tracker please be seperated from "cravings" on other trackers. Wanting to get high and wanting sugary foods are completely different things, and both could occur on the same day, for different reasons, or -not- occur on the same day, but it will currently look like they did.
Also, could you add other use related symptoms? The ones I've thought of are "nodding out" (I'm sure there's a more technical term), blackouts, crawling sensations (like meth bugs), paranoia, memory issues, cognitive issues, and maybe the sleep quality (insomnia, restful, exessive) one that I've seen on some other trackers. Also appetite increase/decrease, and shakiness.
