Hi Bruno,
It's easy (though often useful) to think of our respective recoveries in terms of days/numbers, as it gives us something quantifiable to pride ourselves on. However, it really can be disheartening when you slip up and have to go back to Day One. That usually leaves me very depressed. I prefer to think of it not just in number of days, but also as a lifelong process that will have some peaks and valleys. I do everything I can to make the peaks last as long as possible....and here's the trick...I do it one day at a time. Everyday I commit to being sober on that day. Am I always going to be successful? I hope so, but I can't guarantee anything. It's the best I can do!
