My mom has PD and loses track of time and doesn't take her meds "on time." HELP?

You can set alarms in a smart phone and label them for taking meds. That's what I did to help me remember to give Dad his PD meds on time.

There are lots of timer options for meds. For instance you can get timer caps to put on the bottles that will tell you how long since the last dose. There are also pill boxes with timers. Some have alarms, some just let you know how long since the last dose.. Search "medication timer" on Amazon.
