Hello There!!
If you feel that the Green Smoke is not working well for you, or that you have many issues. You should return it now and get your money back before you can't. Remember, you aren't obligated to keep the Green Smoke if you don't like it. Don't like it, to many issues....I highly recommend returning it! There are many other E-Cig companies out there that might work better for you!
Good Luck
