Quitting smoking before it's too late.

Hey guys,

I'm a 25 years old healthy male. I started vaping and stopped after 3 weeks as I noticed I was already chain-vaping.

I started smoking this week, felt really bad at first but then I've found out that sugar helped with nicotine poisoning.

I smoked today. 8 cigarrettes. I don't need this and I'm kinda anxious as I have a headache and I'm wondering if I already fucked up everything.

I want to quit. I just don't want to get into this trap. I'm anxious now, scared of having already thrown away my health.

I could use some words of inspiration, please. Help :(
