It will be 3 days of no cigarettes tommorow morning for me! I'm so happy, omg! The longest its ever been since I started smoking 3 years ago! 510 is a miracle! I've tried patches, gums, inhalers, cold turkey and nothing helped. I feel a bit insecure when I vape, because I keep waiting for the battery to run out, but I'll be getting Riva soon. Omg the battery just died on me as I was writting this. Not impressed. Back to an automatic with carts now until the manual charges, yuk!
