so I have made my first ever diy liquid, chocolate strawberry, although i relly do enjoy the taste of it the nic level seems a bit high, i bought 54mg nic from L&T, used 2ml in a 10ml mix making it just over 10mg liquid as i usually vape at 11ml. i left it on a radiator for approx an hour then put 2ml in a tank just to taste it, it all tastes good but I seem to be getting slight head rush from it and now I'm worried the nic base isnt actually 54mg, any one else ever encountered anything like this? any help would be appreciated cheers
