I've always found that juice seems a bit flat a day or two after opening (when I say flat I mean like more watery if that makes sense). This morning I gave my juice a good shake before using it (I drip so much into a milk top carton and then dip the bridge of my evo atomiser in that). I don't know if it's my imagination, maybe because it's my first vapes after a night's sleep, but it seems to have a bit more body and is producing more vapour than yesterday. Do any of the juice ingredients tend to settle on the top or bottom? I'm thinking when the juice is first opened it's already had a good shake up in the post.
