Further update and two questions: Following my doctor's suggestion I took 2 Senokot (in its generic form, without the docusate sodium) last night and two late morning, in addition to the Miralax. Let's just say it was a long, uncomfortable day, but I've finally begun to feel like myself. Both my PCP and GI doc want me to stay on the Miralax until my GI appointment on Aug 11. Now the question: if the Miralax really isn't working--I do believe it was the Senokot that did the trick today--what can I take instead of Miralax. Of course I'll discuss this with my PCP but other suggestions are always welcome.

The second question: can the accumulation of Miralax cause nausea, especially if you throw in the Senokot? Everything I've read says that nausea can be a side effect of certain laxatives, so I'm wondering if this has been a generalized reaction.

As always, many thanks for your generous and insightful suggestions.
