The constipation can be managed (the nausea too for that matter) and the grogginess (from pain meds) should subside in a day or 2 after your body chemistry adjusts to the meds. I can't even begin to imagine how you are making it without them. You must be one tough hombre or a Navy Seal or something. Of course there is always the concept that healing is not enhanced by suffering chronic pain.

I was nauseated for quite a while post Tx as most of us were. You have to work at managing it. It's part of the misery aspect of the treatment. The chemo is very toxic, especially if you had Cisplatin.
