Vomiting relieves symptoms

I have discovered that making myself vomit (sometimes I have to try it several times) will relieve symptoms. Last night I had the first attack in 4 1/2 months (which is great news that I attribute to taking probiotics). It took several tries to get anything substantial to come up but I was able to lay down and go to sleep. about 2 hours later, I woke to a burning pain between my breasts. I tried vomiting again - only a small amount came up but I immediately felt better. Anyone else have a similar experience?
