"i was prescribed with propranolol 80mg for anxiety while driving... i was so scared to drive! my mouth would go dry (my mouth would stop producing saliva - seriously!), i would sweat under my arms profusely, my legs would feel like jelly after stepping out of the car, my feet would twitch as i was so nervous! i take one 80mg tablet before driving (i sometimes take two if i&#039;m feeling very anxious). i resumed driving today and it was a much better experience! i didn&#039;t sweat at all, i don&#039;t feel scared, my legs don&#039;t feel like jelly, my mouth still goes dry but it&#039;s not a huge problem like it was - as i could not produce saliva at all as i was so nervous! lastly, i do not twitch at all! i do not have any side effects, such as nightmares."
