I am using a smok ego cloud sub ohm kit and flavor was awesome when i first got it but after about 2 or 3 weeks the flavor has been muted, i have changed coil once every week or two and it makes no difference, i thought it was vapers fatigue but friends who tried it when i first got it have tried it again and about 3 of them say the same thing. the only thing i can think it might be is that i was using mostly 0nic as i was waiting for nicotine base to arrive but even juice that was premade with nicotine has diminished in flavor so im not sure what it could be. any ideas? cheers
