I'm into my 3rd week of not smoking and feeling pretty pleased with myself.
However, if anything, the weird and wonderful dreams (which I can only assume are from the Champix, as I never had them before - and they are a common side effect) have been getting even more weird and, in the case of a couple of nights back, pretty disturbing. However, that may have been because I had the 2 tablets that day relatively close together. I'd missed the morning tablet, so didn't have the first one of the day until about 5pm and the 2nd about midnight, rather than the usual 10am and 8pm.
Still sticking with it, though and will make sure I stick to taking them at the same time each day.
