Congrats on quitting Sparklez, your much stronger than I was (my next attempt is hypno) but I did find, and my doc reccommended, dont even try to quit or cut down until you have been on them for the reccommended initial time (leading up to your chosen quit day), then you will notice how easy it is, I genuanlly kept forgetting I was even a smoker, and would just distract myself for a minute or so and then I'd remember again in a few hours! I guess what I'm trying to say is it will be much easier in about a week. Also, make sure you take them with food & don't take them too close to bed time or the nightmares will haunt you for months!
Unfortunately I had to stop taking them and I'm still getting over the side effects, (plus I had quite a few smokers around me & lots of added stress)
But with saying that, they DO WORK! congrats again, I wish I was in your shoes right now, but I'm off down another path asap, and I'll see you at our destination!
