i have the o3 elite. Alli remember is...i put on the earscope...within a minute my nose starts itching...i noticed more energy...clearer head...defintely something going on...For what ever reason i feel NOTHING from this machine...AND I DONT UNDERSTAND WHY!!!!!!!its very frustrating. I had a dream that this was my life line. I called the company many times explaining my situation...expressing that there has to be something wrong with the machine or how im DOING IT...or something. I smell ozone coming out...so for sure ozones coming out...why i dont feel anything is BEYOND ME. im going to try a rectal insufflation withou humidiying it through water...see how that works. Im about to do an ozonated coffee colonic...I do remember tho...i ozonated water for a while...drank it and felt it burning in my veins. So...i def felt that... I have my syrringes coming this week...imma do an IV...ill keep you posted...where you live? LA perhaps?
