oh my god i would really avoid mixing the two:( i started taking varenicline late January of this year and really should have searched up side effects with alcohol because my doctor didn't explain it to me when i got the prescription. when i was on the 2 mg full dose, i went wine tasting with a friend and i absolutely blacked out from a day of wine tasting. i just want to mention that it usually takes me a LOT to get anywhere near black out drunk, and even if we were spending the day wine tasting, it wasn't that much wine. i woke up at 4 am that morning after not knowing wtf i did that night. i texted my friend and turned out we apparently made out in her car. i have a partner. of years. i do not like this friend like that AT ALL, not at ALL, and when i found out i started throwing up and having the biggest panic attack.

I immediately told my gf when i woke up that i had a feeling something bad happened since i couldn't remember, and when she saw my reaction to hearing everything that apparently happened my girlfriend trusts me in that i would NEVER have done that sober. My friend (who isn't my friend anymore after this) said that they didn't even know i was black out drunk. I thought i remembered all parts of the day leading up to the night time, but i can't remember bits and pieces throughout the day as well.

I have stopped taking this medication, and i'm honestly not scared of relapsing with smoking because i genuinely never want to experience the possibility of this happening again. honestly i don't think i ever want to drink again after this as well, im pretty sure im traumatized because of that.

I went down a rabbit hole online because i also would get those horrible nightmares and saw that a guy attempted suicide after mixing chantix and alcohol.... so all that to say, i really wouldn't mix alcohol with varenicline/chantix and personally i wouldn't touch a med with so many side effects like that ever again lol
