I think I will go with the cipro as I can hear that there is something going on in there although not coughing...just slightly congested and tight in morning and by arvo clear... he's had haemophilis the last few cultures and I kept saying to doc that it wasn't going away...no wonder it is resistant to the antibiotic we were using!! Can I keep the arginine if not doing GSH whilst on cipro...what is the usual protocol of GSH when using cipro? Thanks Hope
