Miralax worked the best for me along with Senokot-S. Milk of Magnesia can work well too but it's much easier to overshoot with it. For me being on a daily schedule of the above worked best.
I'm glad to hear the Valium helps you sleep...sleep can be very elusive in the early days. You sound like you're doing great! Keep well ahead of the pain with ample pain control and you will be able to move around more. Several 5-10 minute strolls at this stage is a good goal. Sitting was very uncomfortable for me so I mostly avoided it at first. It does get better in time. I recall turning my first corner at around 11-12 days.
Thanks for keeping us updated and keep up the good work.
