Well I bought some Dr Oetker Glycerine from Tescos and thinned it by 25% with De-ionised water as it was very thick then mixed 75% premixed liquid with 25% glycerine and it seems to have turned out fine, the flavour is still there but it is now less harsh. I bought Vanilla and EuroBlend from Cloud 9 and the flavours are quite strong to begin with so that has probably helped. I still think it is too strong as far a nicotine goes so I think when I start mixing properly I will go for 16mg/ml or less.
