How to eliminate nicotine cravings?

Hi, I am on the pill so really cannot afford to smoke anymore due to the dramatic health risks. I am also so so sick of smoking and quit for a couple of months but I am feeling a relapse to smoking coming on as I have lost my self restraint. I was wandering any tips to cut out the cravings that anyone has? All the nicorette products didn’t really do much for me (e-cigs inclusive) so was wandering any natural alternatives to cravings?! Thank you
