Me too Joe. I am 80. Unfortunately, I also have neuropathy with balance issues. Therefore I am unable to walk much in the way of distance. I am trying 295mg of Lizness every other day which seems to be working. However, it is in the $400-550 range for 90 day supply. Medicare will pay 80%, however, I am applying for the Manufacturer's PAP. BTW, I have gone though your same regiment with Ducolax and Miralax. They work, however it is always a diahrhea type event. Bummer. God bless you in your journey Joe. Charles aka brotherchuckles80
