I am not sure the safety of using Smelling salts BUT I have used them a few times and has helped when nothing else has helped. I have tried almost everything ( I am sure there is a few I may have missed) It doesn't take it completely away but something is better then nothing. I have been chronic since 99. I have seen Young, Sheftell, and Rozen to name a few. I would be careful if you have heart problems, as it does make it race. Just info not a cure. PF wishes to all
