Hi KD: Just wanted to let you know that I bumped up my oxy to 10 mg dose and it has made a big difference. Hope it might do the same for your husband. Also I’m really finding value in the salt water baking soda mix, which I’m talking every 30 minutes or so. Whenever I accidentally touch an ulcer and am in pain, i swish some of that and find it calms it down a bit. Also helps with phlegm, which has become a big problem for me.
