Have posted on here and another forum before, and also gone into the b&m where I got the tank from to no avail, i'm preety much done trying to solve this problem after 3 days of researching I am so annoyed i'm now smoking cigs again 
I'm using the iStick 100w with atlantis 2 tank, I was using the 0.5 coils at around 30-40w previously and having some issues so got a replacement pack of 1ohm coils. This seems to of amplified the problem 10x and is totally unusable, no matter how much I prime the coils/leave them to soak/take primer puffs/start off at a lower wattage and gradually increase it is always a super harsh vape and taste like absolute sh*t, you definately couldn't take a hit longer than 2 seconds and have your throat still intact.
All the juices I have are high VG from 70/30-90/10 but from what i've read 70/30 should certainly be no problem. Not sure what else I can try here, nothing seems to work.
