To be honest with you they were so many and I have no idea how long I was on them all I know is they all did not work for me at all nothing at all work for me because my body says no no no no to any of these medication‘s. from reading the comments from many many many people it looks like most people have no trouble at all of the medication‘s that I had many problems with it’s just that my body is not like other people‘s body and I’m like wow this one did super Duper honest medication not me so the bottom line is you know what I was a learned each of us is so different bodies are different and we just have to work around her own bodies and figure out what works for us I wish you the very best luck going forward!!!
