Feeling sick early on...???

Has anyone else had nausea within the first few weeks? (Not using Champix.) I've just noticed the last week after 2 and a half weeks of cutting down and having a few smoke free days and mostly no smokes for the last week or few days or so (its hard to tell the exact times for me because of my Dissociative Identity Disorder) because I've been feeling really sick for the last few days that I know I haven't had any smokes and it feels like I want to vomit constantly at the moment, which makes eating and even sleeping very difficult, although sleeping has been difficult enough without the nausea...

I have been using patches as well during the day, since I can't use the Champix without severe nastiness and hallucinations happening and nothing else seems to work but, should I be feeling this nauseous this early on...? I WANT to quit! And have tried a few times before and succeeded for about a year or so both times, (my 4th attempt, as I know Champix causes nausea but after I tried it the first time I found out I couldn't use it) but I have never had this nausea before when not using them... I've tried drinking water, milk, tea and everything else I can think of and even tried eating everything I could think of as well to see if anything helped but so far nothing does... I'm tryna tough this out but, although I have a severely high pain threshold, I have a crap tolerance for feeling sick (Im a regular iron guts, and can eat/drink anything and not get/feel sick at all so, this is really really not fun for me, feeling nauseas at all...) and I'm not quite sure what to do about it...
