I'm very sensitive to medication.. so most of it blocks any kind of creativity. I have to take antideps and betablockers to make my life manageable, but those are the lesser evil. By the by, Beta blockers work well for my anxiety, I rarely have panic attacks nowadays. You should give them a go. Also, when I was quitting weed, my anxiety and insomnia got absolutely horrible.. it gets easier after a month or two (smoked for 6 years).
