Basementcat, I tried all kinds of fillers.....including the PTB. Actually, I always go back to the blue foam. If you haven't tried it, you should. It's the very best....my opinion. Also.....maybe keep working on your roommate about vaping inside....that would help change the times/locations part of the cig habit. Have you heard of stealth vaping? When I'm at a place where I can't/don't feel comfortable vaping, I find the nearest bathroom and just have a couple of drags. Works great and there's no lingering order/vapor. Part of the secret to quitting for me was actually being able to vape....just two or three hits....whenever I felt like it. That way I never really got to the point of just craving a cig. It's different for everybody, I know. But the stealth vaping here and there (instead of saving it all up for that 5 minute outdoors cig break) really worked for me. Good luck. Glad you're figuring it out.....it'll come. The more you vape, the worse the cigs will taste. Pretty soon you'll be in a spot where you have a choice......cig or vape....and you'll find that you prefer the vape. Hang in there......and congrats on having a 7 month old! Babies change your life (for the better!) don't they?
