I don't know what to think about all of the things that are supposed to help or prevent PD - but an hypothesis about this could be made that relaxing the mind with substances that we label vices and unhealthy - as with everything else- if used in moderation - not excess - probably is good for one's health . people have to be relaxed to feel humorous - definitely not a natural thing for most people.

Wound tight is something i work hard to avoid with such muscle reaction to it. in the evening I have sinemet build up....but you have to have a mind set to go with the relaxation. Thus, the bubbly provides both.
