Ive given up for 2 years now and I hope my experience helps you.
I vaped for about 2.5 years. I was getting through 2 elf bars a day (I know- really bad). Anyway, it was making my anxiety go through the roof so I knew I had to give up and I was just generally disgusted with myself because my entire life revolved around having to ensure I had enough vapes on me at all times. I tried to taper off but it just didnt work because I would be counting the minutes down until my next puff and the time in between became sheer torture. It became all I could think about. I then tried nicotine substitutes but actually that made it worse because it meant I could use the mouth spray continually throughout the day at work (whereas with a vape I had to go outside)- I ended up using it more than I was vaping so that backfired spectacularly.
So I decided to quit cold turkey.
I got Alan Carr's audible book "easy way to quit vaping" and I listened to it every single day, at every single opportunity I had. The Audible version was much more helpful for me than the kindle version. I bloody love Alan Carr - he is the GOAT. I listened to that book over and over and over again. Every time I was able, I'd listen to it. I started to know it so well I could recite along with him. Every time I felt like I was crawling out of my skin wanting a vape, I'd put Alan in my ears. It helped massively and frankly, I dont think I could have done it without him. I literally brainwashed myself with his book.
The first few days were bloody awful and I was a snappy, short tempered bitch to everyone around me (I did apologise to them lol). I also felt really, really low- nicotine affects dopamine levels on your brain so be prepared you might feel like this for a short while. If I recall, day 6 was the worst. I remember driving in my car going to work feeling as if I was never going to be happy ever again. I remember thinking if this is my life now, I dont want it any more, I am going to go back to vaping if it means I am going to feel this shit for the rest of my life. But I held on. I promised myself, I would give it at least a month before I made any decisions to go back to vaping. I kept on listening to Alan. I clung to him like a life raft.
I also got myself some nootropics to help my brain increase my dopamine levels- supplements like L tyrosine, magnesium, NAC and Rhodiola Rosea etc.
Then, a weird thing happened. After about 2 weeks of feeling like utter shit, I was again in my car and a banging 90s tune came on the radio. I suddenly felt happy. The first time in two weeks I had actually experienced a good mood and I thought OMG I can feel some happiness again- maybe my brain isnt totally fucked after all. This spurred me on. I still had carvings at this point - particularly after meals and first thing in the morning were the worst but I reminded myself they only last about 10 minutes and they do subside. Physical cravings for nicotine go after 3 days but it's the psychological cravings that last longer. I carried on going. At about the 3 month mark I realised I was barely thinking about vaping at all. I'd get the very odd craving of "wouldnt it be nice to have a vape" but they gradually got weaker and weaker until they disappeared completely.
I can honestly say that after that first year I never thought about vaping at all. Not even once. I'd see other people vaping out and about and I never feel envious, I can honestly say, if someone offered me a vape right now I'd be like "ew, no thanks" so please dont believe you are doomed to feel like this forever. The idea of vaping disgusts me now and I cannot believe I ever even liked them.
You CAN do this, I promise you. It's the best thing I ever did and if I can do it, you can too.
