Very proud of you both for quitting

My Dad has been chewing Copenhagen for as long as I remember and I pray he doesn't lose his jaw.
Anyway - you know - I want to say it's possibly your teeth/gums - then again your sense of smell and taste come back so............hmmmm.... I would get checked for periodontal disease.....I would just think that it has to be from your gums or something. Do you floss regularly? If not, please do so. Will save you a lot of trips and gum diseases.
It could be the gum???? Nicotine has it's own weird taste to it so maybe it's your view that nicotine tastes metallic? Hmmmmmmmmmmmmmmmm LOL
Either way - don't dip - metallic taste and all - at least you'll have your teeth and jaw.
Much success
Laurie
