I don't know, Tex. I don't remember having C. I was having some D most of the time with severe episodes/attacks of nausea then vomiting then dry heaves then lots of explosive D. It always progressed in that order for the "attacks" except toward the end..just before I went on meds..the dry heaves and explosive D would overlap.
I guess we all had our own little "quirks" with this stuff.
