Need an advise to sweeten my DIY eLiquid

[BlackPurple]

i have done my DIY eliquid with success result..good vapor and good throat hit just like i love it..
the flavor is kinda mess it up a little bit..it got very good flavor BUT not sweet enough.
when i vape it sometimes its good, sometimes its bitter, sometimes its tasteless..
at this point, im thinking to add some sweetener on it..but this is where i need some help.

i have survey on multiple store for stevia (not interested in other sweetener) and i found 2 type of stevia.
1- Equal brand : claims that 1 stick = 1 spoon of sugar.
2- Surevia : claims that 1 drop = 1 spoon of sugar.

i want to ask. how many drops do i need on each product to sweetened up my 10ml liquid without fry my coil.
im afraid if i use Equal, it not sweeten enough with 2-3 drops and force me to use more.i dont want too much non-PG/VG in my liquid. also im afraid if i put 1 drop of Surevia, my liquid will be over sweet and fry my coil. please help me.
OR
is there another way to create stevia liquid sweetener?like tablet or powder?i can use them?

I don't know much on the topic of stevia, or if the liquid stevia that you found is safe. But if it is, I'd recomend diluting it in PG before using. Maybe 1 drop in 10ml of PG, then one drop of the diluted stevia in your mix.
