I've been vaping the same tank & Tobeco coils & I usually use .20 buy have been chain vaping & my lungs are irritated so I tried to go from 6mg to 3mg but to weak so I split it to make it 4.5ish. I figured using a higher resistance in the .50 would weaken the vape but it's stronger & I'm confused cuz I thought it would be weaker? My 5 mg juice is now way to strong so I had some 3mg laying around & used that & it actually hits perfect except it makes me dizzy, light headed, hot lol. It's crazy, I know I've used the .50 before & don't remember noticing a difference? What is happening, why is 3mg making feel weird in a higher resistance coil? Was I wrong in thinking the .5 was going to hit weaker then the .2? That's my other question besides what the 3mg has me all weird lol. Like after a few hits I feel weird, shouldn't happen as I chain vape 4.5mg all day long since I'm not working. That's always been out the .2 coil but like I said I've mixed & matched before when supplier doesn't have the lower ohm & I never seen a difference, so weird. I don't get it?
