She is dopamine depleted but still extremely stimulated - that is reason why she doesnt feel high anymore but cant quit moving etc. It will pass in a day or two but i advise to eat something, u need proteins, fat and sugar, drink water or isotonic drinks, avoid caffeine, take benzodiazepine (10mg diazepam or 0,5-1mg alprazolam, 0,5-1mg clonazepam, 1-1,5mg lorazepam if she is not used to benzos, maybe even less and take more if needed later). Low dose of codeine, dihydrocodeine or other opiates/opioids can help but its very habit forming. Dont take tramadol. Calcium, magnesium, zinc, b6, valerian root tea and melatonin are good options. Ibuprofen for migrains, promethazine/dimenhydrinate/diphenhydramine are great for nausea and they make u sleepy but they also make my heart race even more.
