No, but it's funny you post this....I brought home a bottle in FEb. and today I went to use it and it seemed to have seperated. I am worried that it may not have survived the trip with the "pressure " idea. I was able to press on the cap and it went in....and did not POP when I opened it....anyone have an opinion???? I love the stuff and always want to bring some back, but this is the first test.
