Sorry for the gross post, but periodically throughout the days that I drink Soylent, I'll experience an awful taste in my mouth / bad breath (tastes like the one time I tried cat food), especially when I cough or sneeze. Eventually, perhaps once every couple of days, I'll cough up a particle of something, which I assume is a tiny piece of Soylent buildup lodged somewhere in my throat, which is probably the cause of the bad taste in my mouth.
What's strange is that (A) this doesn't happen to me with anything else I consume, food or drink, and (B) I haven't seen anyone else complain about this. I didn't notice this problem until I started getting packages that expire within a couple of months with darker powder. I don't have any known food allergies. Has anyone else had this experience?
