Respite /ˈrespət/ Noun – a short period of rest of relief from something difficult or unpleasant.
Wayne had a nice respite from his diarrhea yesterday, NOTHING during the night. Total volume only 500cc’s. Whew!!! Something was going his way yesterday. This could be a real break. What this seems to mean is, it seems he is responding to the regime that he is getting for his cGvHD, and he could get a long respite.
