I mentholated a disgusting juice when I had a cold and couldn't taste anything. I could taste the menthol, just, so that got rid of a little. I too have at least 100 ml of juices I bought when I started and am wondering if I can do a swap if possible although I may have to give them away with difficulty. Mine are assorted tobacco flavours, some made with double strength FA concentrate, chocolate that's never seen a cocoa bean, coffee that tastes like bad instant, either 100% PG or 70/30, bottles between 10 ml and 30 ml, all 18 mg/ml, most unopened. I've been hanging onto them in case I run out but a shop opened nearby and I can get juice there if I need to. I don't buy cheap juices, average is a fiver for 10 ml on premiums because I find you tend to get what you pay for. I was given a little Simply Tobacco once by somebody who thought that as it was so cheap for 100 ml you can't lose. My answer, you can! So apart from quality juices I also make some of my own, specialising in Vanilla Custard.
