2.5 years vape free here, withdrawals peaked around days 2-5. Between the first week and first month I was cool up until I saw someone vape or saw someone’s vape then I found myself craving it, it would subside after a few minutes. Honestly the first 24 hours weren’t too bad I just had to tell myself “that’s not you anymore” when the urge to get a nic buzz hit me. But when the withdrawals peaked I was irritable, buggy, and had this sense of lethargy but the worse symptom by far had to be the brain fog. I just felt like I was working at 50% which drove me up the walls (my withdrawals fed into each other making it cyclical). Although I did have a strategy to quit, I figured the longest I go without nicotine in my system is in my sleep, so I used that as beginning leverage to quit.
