Ok like I have told all of you I have been taking norcos 10/325 for about 6 years and two and a half years before that I was taking oxycotin 80mg now I abused both with the norcos it was atleast 15 to 20 a day and with the oxycotin I was taking atleast 4 a day now the question I have is when all of you were using did you ever experience chest pain and shortness of breath this has happened to me many times in the past and I always end up at the er. Plus I would have eratic heart rhythms which really scares me alot. So if anyone has had this and knows if the meds are the reason please fill me in thank you sincerely Uppy
