Tips for quitting smoking?

I’m trying to quit smoking again. Last year I managed to stop for several months by using vape and gradually lowering the nicotine until I didn’t need to vape anymore.

Unfortunately, I slipped back into smoking when I moved to another country a few months ago. I’ve decided it’s time to quit for real this time, but I’m wondering if there are any nicotine patches, gums, or other aids you’ve found in drugstores that actually work.
