  • Being part of the Bulimia Recovery Program (BRP) has been an integral part of my own success; I am proud to say I am at almost a month free of bingeing and purging! One of the most important elements of this program is access to Shaye’s tremendously helpful guide for bulimia recovery, in which she uses her own experiences and that of others to literally guide you through many aspects of the recovery process (such as learning structured eating—so important!). Seeing so many other wonderful people break their b/p cycles and engage in structured eating helped me to see that I could do it, too. ➤➤ http://t.cn/A6Pq6ilz
