I would go to
www.4meridia.com that is the official website and they should have info there on what meridia is and how it works...i sure know they can explain it better than i can!
I hope the xenadrine you're on is the new one (efx) without ephedra. Look out for ma huang/ephedra that is some bad stuff! Forget about energy, I felt like my heart was going to burst out of my chest when i was on a supplement that had it in it!!
Good luck with all of your weight loss efforts...hope to see you in the chat room one of these days
