Painful

My pharmacist told me to take benefiber three times a day and that I could use the miralax at night, as long as I didn't take the two together I could take them on the same day. I also tried sugar free hard candies (just don't do too many of these at a time). The combination got me going more comfortably within a few days.

Also, get in as much fluid as you can. Seems like upping my fluids to 80 oz/day has helped significantly too.
