I'm on 2 referrals.
Sadly I must say that all of us including me are a bit unhappy with Jake. I'm geting SUPER dry in my throat for over 6 hours, so I'm probably allergic to something, my other friend just feels real sick when taking Jake, he even puked. And the last one is still hungry afterwards 
EDIT: I've figured out my issue, read my "2 weeks on jake" experiance
