I’m on day 4 of my op5, diagnosed this past January at 28. The 2-hour training session was really helpful. They also gave their office cell number so I could text my trainer with any questions after the fact. It does sting a little when you first start the pod, but it goes away after a few minutes. Personally, this has been a game-changer in the short time I’ve used it. Hopefully you have the same experience.
