Hi, don't know for sure but would advise not too, it makes you hungry so I'm told, if it's ketosis breath you're worried about I carry a thing of gold spot round and have a squib if i feel stinky x
go with Trident - tis the type that you cant chew for long if you know what i mean. I chew it till the mintiness dies down then chuck it away. I know a lot of Miniminers use trident on their CD journeys with no ill effect xxx
