2 weeks now. Still on patches and gone back on the lozenges. The lozenge lasts a good 40-50 minutes to waste away in your mouth whereas the spray was too quick. I find using the lozenge substitutes for a ciggie quite well. Haven't had many cravings at all. They come and go, mostly in stressful situations. I'm using my time well though. That time not spent sitting on the couch waiting to go for a ciggie. Feel more energetic to get stuff done around the house. Ciggies really did drain me of any energy to get anything done.
