Is it ok to wear a patch during the day and smoke at night

So I have had a very hard time quitting, I’m really not sure if I am fully ready. I’ve been struggling on and off quitting for a year now. And a few months ago I went through a bad break up and now it’s even harder!!!

I have been smoking a lot, like a pack a day which I don’t normally do. I don’t want to smoke that much. I do have an easier time, with the patch, to not smoke during the day. But once 9 pm comes around I want one so bad and I’ll take it off and have 2-3.

Is it safe to do? I use the 21 mg patches.
