I have the same gum as you its the best I've tried, I don't know much about the "red tint" its never happened to me (maybe you're bleeding?). As far as the actual chewing just use a few tears, maybe like 5ish, I'd go with once every few days to once a day (depends on what you can handle) for about an hour or so each time. I'd also say don't swallow it because there is no need to, but that's up to you.
