Seriously, this is the best time EVER to give up smoking. Get on the vape, or get some Niquitin-mini, or just go for it... for cold turkey, it's a week of cravings which improve after 48 hours, and are eased by your BP lowering, which will give you the oddest feeling (in between cravings) of being less anxious and wound up than in living memory.
You'll possibly save your life,or possibly save the lives of others by minimising your risk of taking up an ICU bed.
