T.H.
I got the ear staple 6 months ago. I got it because, I had suddenly over the past year started gaining 3 pounds a month. (I think it was due to hormonal changes getting closer to my 40th b-day.) I have not lost any weight, but very important for me, I have stopped the 3 pounds per month cycle. I have maintained the same weight for six months. If it was due to the staple or not, or just a placibo effect... I don't know. I am just very thankful the weight gaining has stopped.
I am suppose to get this staple removed soon. (suppose to do a switch out every 6 months.) I am satisfied enough that I will get another ear staple after the two week waiting period.
Hope this helps.
