Sebastian- I don't know about bulimia, but I did suffer from anorexia when I was 18.
Being in my late twenties when I tried the Master-Cleanse for the first time, I don't know if it will help you with your bulimia, but it may make you love you body and want to treat it with love from now on. I know eating disorders are not really about what our outer selves look like -- it's a control issue. For me, my life was so out-of-control & there was absolutely nothing I could do about it & took control of the one thing I could -- what I put in my mouth. Eventually, I was able to look in the mirror & really see how sickly I looked (about a year later), and I haven't had trouble with food ever since. At least, nothing drastic.
Good luck to you, Sebastian, it is possible to heal yourself.
