While I agree, it's not so easy. I mean how many times do you see posts on here about somebody eating pizza or a cheeseburger one week after having bariatric surgery (not to suggest you can't incorporate them in a balanced diet) . Unfortunately most of us have addictive behavior, and to get ahead of the curve you just have to acknowledge it and actively attempt to improve it.
The OP acknowledges this, and I think was trying to justify their behavior as not that bad. But at least she's willing to learn and hopefully will use that knowledge to make better decisions going forward.
I mean there's a big difference between thinking smoking will just delay your healing, and learning that it could cause a perforated ulcer causing you to completely get cut open possibly septic and have a visit to the ICU for a few weeks.
Honestly I've seen that ****, and I'd rather them just kill me than put me through it.
