I have never heard of that. Interesting. I have Bulimia myself. But I throw up all the time even when I don't want to. I have a gastric bypass and they think it is due to that. My lowest weight was 67lbs at age 16 and I went up to 275 lbs when I had my bypass. I am now 174lbs. You would think I would lose more weight with all the vomiting but I guess this is where I am supposed to be.
You have my sympathies and I am glad the meds are working for you!
