I'm not too sure about how long out b4 you can take diet pills....I'm 1 year and 6 months out.....AND I FEEL GREAT!! I do at times feel like the weight was coming off very slow, but it was ok. I went thru a down fall about March of last year to about the end of 2013 with family issues, do quitr naturally I wanted to comfort eat. But long story short, things are much better and I am also mow a part of a health and wellness business where we have products, with ALL natural ingredients, to help you loose inches, weight, multivitamins(that we definitely need), hair skin and nails, a Ultimate Body Applicator to help tighten tone and firm the body parts you wrap and much much more. Why dont you visit my website @www.wrappednfavor.myitworks.com and then email me at wrappednfavor@gmail.com and let me know what you think. Share this info with all those you know that may be in this situation. Take care!
