Right guy's,I've been using salt nic now for last few months,at 10mg strength.now it's too strong for me in a rta,so I was advised to get a mtl tank which I've now got,2 in fact,anyway I'm using one tank with a alien 0.7ohm coil I've got the flavour and hit now thanks to you guys but after 4/5pulls I get a slight head rush or type of headache which is telling me nics too strong 10mg.thing is I've got 250ml of this juice I love mixed at 10mg.so remember when we all first started back in the day with cleromiser pen type ecigs,I forget my first type,but I vape 18mg juice and I'm sure it was a 1.8ohm coil.so would it be worth while putting a 1.8ohm coil in my mtl tank would it calm the nic strength down ??? Compared to the 0.7 alien
