Don't take this the wrong way, but I'll throw in my 2 cents....You said he was loose yesterday, and now no "product" right??
Same thing happened to me
last week.(Yeah, I know it's a pet site, but I think that works mostly the same way)
I thought it was a bit of the 24 hour flu or food posioning, but it sure cleaned me out....then nothing for 5 days
Maybe it takes a while?? It was funny b/c I thought I should feel bloated too, but I felt fine.
Sorry if this was too much info
