Does anyone know if it's ok to cut the 1 mg tablets in half? I tried Chantix several months ago and didn't quit. Now I want to try again. I don't have the .5 mg tablets left, so I thought I could just cut it in half. Then I read about when you cut a controled released med in half, you get too much of a med in your system all at one time. Not sure if this applies to Chantix? I took 1/2 pill yesterday and kept waking up all during the night. Is that possibly a reaction to Chantix?
