Welcome, but you must be informed, this is a No Nicotine site. We quit cold turkey. You are certainly welcome to join us, but not while you are using nicotine in any form.
That being said, it really is only hell on earth the first three days, then it sucks for a couple weeks, then it isn't so bad anymore.
Read everything you can about it and go post day one with the July quit group once you've thrown out the gum and all other forms of nicotine.
