Unless I totally misunderstood the OP... she wants to DIY not buy commercial liquids??
Spazing or not. I know the pain of this Question... I do prefer tobacco flavs/unsweet even after all these months..With the sweet flavors for a short change of vape..
My solutions has been to buy my fav low to nonsweet commercial liquids and add a drop or two of flavoring to them...Cubin Cigar, winston,dunhill,benson and hedges, jantys- heavy shag isnt sweet but major strong and a few other tobacco flavors are very low on the sweet factor and they all hold up to cutting, providing you dont vape 36 mg to begin with lol. Totally wickets "unflavored nic" liquid, has the slight hint of a tobacco flav as does Fresh or Mild ecopure..All the ones listed above allow you to use them as bases for your DIYing..So you'll have the tobacco background ( toned as far down as you prefer) which will allow you to add just a hint of DIY flavorings ( keeping the sweetness low)... I have found Cinnamon to be nice for this (ecigsmokestores Red hot, requires only a few drops in one of these low level-sweet tobacco bases. Or a background( few drops) of coffee, vanilla etc. I would think hazel nut would be a good one..If you like that flavor
( Never refuse to revisit or try other flavors... I have come back to some that i couldnt stand early on and love now...I've had suppliers send me some that I neeever would have tried, and one of them is now my all time fav vape.. taste is constantly changing... Oh, and vape it for awhile. Dont just take one or two vapes, wrinkle your nose and toss it.. Giving it a lil time to get used to pays off lmao
Also, alot of Capella's DIY flavorings or on the low sweetness level.. Good luck
