Hi Susana,
I read your post and wondered if it would be ok to offer some thoughts. I hope so, we have some similar traits I think and maybe something will resonate with you :)
Quit date by 15th via the moon. I'm assuming you refer to the full moon on sat 12th and the strength from that being 3 days, thus taking you up to the 15th? It's a capricorn moon and I see your taurus, so it's in an earth sign like you are and should flow nicely. However the energy lends itself 3-5 days either way, so if you feel ready, you would still be within the energy of this influence :) I get some people think it nonsense, but the same people believe in the power of positive thingking/mind over matter etc and ultimately, it's all the same thing anyway - just using energy to help an existing will you have.
Private - yes! Apart from here. These guys know more than my family and t start with that didn't sit right at all. How can they help me, or you if they don't know us though, we have to let people support us when we're down and our own brain is being a bit crazy.
Lows - yes! A fellow emotional yo yo right here. Hugs to you, it's so hard when you're fighting yourself. Have you considered meditation? I see you have exercise already and you're right, that's fab for craves but for calming my brain I used cigs - now I sob like a baby lol. Less often though.
I think your onto something with understanding the craves. When we smoke, we have craves all day, like every 20 mins or so it starts until we smoke and then it dies down. There are honestly far less craves when you take smoking off the table. Mindset is powerful, as is understand and education of addiction. I don't think we actually quit until we accept we are an addict to nicotine. I know very few people who would willingly accept being an addict and saying "oh yes, see you in 5 because I'm off to fulfill my nicotine addiction". It kinda sticks in the throat - like smoking!
Too much rambling haha. Maybe something will help you. Regardless of anything else, you absolutely can do this. Quitting smoking is the single biggest gift you can give to yourself on so many levels. Even when you crave, just hold on, post, cry, suck candies, sleep and wait and you will always be glad to be a non smoker.
Welcome! xx
