Are you asking or do you know? I'll look into that. Funny I didn't notice it with zopi until I read it as a side effect, then I had it ! Power of the mind. I need to take it with juice and get it down fast? Even something that small I have a hard time getting down.
I just read up and people say it's pretty bad. I'm not going to spend that much money to toss it out. I'll try putting some zopi in a capsule on a day when I can tolerate feeling like I licked the inside of a dumpster.
