I took champix years ago & unfortunately did not stop smoking, wasn't dedicated enough.
I am on it again on day 5 & it has affected me the same way as last time, vivid dreams (which are rather entertaining), however I am experiencing nights of very light sleep, that coupled with feeling a little more tired then normal (I believe also from champix) is exhausting.
I don't take prescription sleeping pills but do take Advil nighttime occasionally.
Is there any risk or interaction I should be concerned about?

Thank-you
