Sling off. I haven't had it on in over 24 hours. I know what you mean about the shaky hands. I think the meds had a lot to do w/ that. I haven't had any meds in a week and even then I was tapering off. Driving was a big emotional step for independence, I have to tell you. I parked in a large parking lot and not in the underground garage. Thank goodness there aren't many people, residents or tourists, in town so it was safe. It would have been hard if I had to make any sudden moves. But I'll take it one day at a time and it will get better!
