I am extremely med sensitive and Chantix is no different. I have been taking my 2, 1 mg pills together, right before bed. I get extremely sick to my stomach-lasts around 45 mins to 2 hrs. I don't dare take my morning dose in the AM but I didn't want to give compromise the daily mg's either so I decided to take both pills at once. Is this effective? As effective? Am I allowing the med to "run out" because of the long time period in between doses? I am on my 4 th wk and I just don't feel different, not as I expected to feel at this stage. Any thoughts would be greatly appreciated!
