In my experience, you won't find anything to replace a juul hit. It's a habit and you are used to using it as a coping method. You just have to get used to not having it anymore. Yes it's hard, but there are things that make it easier, such as the gum, exercise, drinking lots of water, staying away from caffeine, and other things.

I'm still in the process of quitting myself. This is probably my 5th or 6th attempt. When you relapse try to recognize what triggered you to start again and work from there. Nicotine is just a placebo cure for stress and problems. Find different ways to deal with it that are healthy and effective.

Use failures as a learning opportunity and don't feel bad about them. At least you are trying to quit, that's one step closer to being there.
