I had this too. Or, at least I think so … This is going to sound strange, but after taking SF722 I remember having excess saliva and almost like froth. The strange part is that I’m not sure if I dreamt it or if it actually happened. I thought about it just today but it seems so distant (god I sound whimsical). I’ll try it again to know for sure!
Though, just on a side note, this was after I took 5 pills after Thornes recommendations. When I took just 2, nothing happened.
