I used to get them here and there but for the past year or so one builds up every three weeks or so. They are nasty and I hate them. They grow in the same spots only on one tonsil. I can even see the little indents where they grow. When they are big enough I take them off with a tooth brush (have not puked yet, but close). I used to try to remove them in the early stages but I would just end up gagging and cut up my mouth with the tooth brush. I wish there was something that would get rid of these things forever.
