Mum,
Hugs to you.
Don't think of it as being "not strong enough". It's a choice. Choosing a better life, being a healthier person. You have the ability to choose.
We choose every time we drink. We say yes or no. But it's up to us what we say "yes" to. When you say "yes" to drinking, you are actually saying "no" to countless other, better things. Say yes to being healthy, aware and present. Say yes to being the person you want to be, building the relationship with your children you want to have. That's worth so much more than any liquid in a glass.
It doesn't take superhuman abilities or strength. You have the power to choose. Don't touch it, don't pick up, don't swallow, repeat. Every moment you go without alcohol in your system, your mind and body will heal.
We are pulling for you.
