I cant stop eating and purge for a very long time I have took alot of medications but with no effect (prozac, risperidal, (risperidone) anafranil and efexor xr). help please?

If you purge. frequently you may well be expelling the medications you are taking. Please see a doctor. You may get the help you need in a hospital and then outpatient therapy w/someone who specializes in eating disorders. Peace and good health. Purging will also ruin your teeth.
