"No more" can be used at the beginning of a sentence, but your sentence is unnatural. Try "I don't smoke anymore."
Student or Learner
- No more do I smoke.
I googled it but could not find any answers. I would like to ask if I can use 'no more' at the beginning of a sentence?
I was wondering if 'I smoke no more.' would be natural.
Only slightly more natural.
