Because I also have brain chemistry problems other than the PD, for quite some time now I've been keeping numerical data on a bunch of variables measured several times per day. And just today I was at the home of my 30 yr old son (who is a physicist, & loves computers), & he gave me the very program you mention. Once I get the data entered, the challenge will be to learn to do the graphs in a way which allows for discovery of correlations & other insights. Do you think this program will allow for that? If I can take such graphs to Mayo, it may increase my chances of getting the help I seek. Thanks so much for giving my situation your time & thought. M. Dawn 56/6
