In my opinion the best option to get out of the crash is a benzodiazepine. I took Xanax and it helped me end anxiety and insomnia. It was a hude relief. I quit Xanax after 2 months.
It can help, but my anxiety was so bad it did very little during the crash.
IMO if I had discovered Prazosin during the crash it would have been a massive help. Also just straight over the counter GABA in high doses seemed to help during the crash.
