I've had the Eupho for 9 months or so but never had much luck with it. I hadn't used it for many months until a few weeks ago. For some reason, I decided to give it another try. I've used it 2 or 3 times so far in these last couple of weeks and the sessions have been amazing. Yesterday's was the best so far. My body starts reacting immediately upon insertion. I only had about a 1/2 hour yesterday...
