HI Tiny2018 - first I want to congratulate you for how far you have come!! You have done an amazing job at implementing strategies and techniques to help you through those tough moments. Usually day 4 or 5 is the hardest part of the quit as nicotine is leaving your system and your body is trying to adjust to the new normal. All those withdrawal symptoms are actual signs of healing, unfortunately they don't feel great at all.
Also with Champix, it does take a while to fully work into your system, so your body is going through a lot right now. Remember to be easy on yourself and continue to use the 4Ds (Delay, Distract, Drink Water and Deep Breath). Maybe treat yourself to a nice water bottle - you deserve it after all this hard work.
Also check out other threads and maybe create fun Quit Kits
, and other Distractions
Keep up the awesome work!!!
