Stop me from voluntarily relapsing

Today is day 5 for me. My last time smoking was last Sunday night. After a joint then, I threw away all the weed I had left. I've been smoking daily, multiple times throughout the day, for 6 years. I know how much it was getting in the way of success in my life and that I needed to stop. I enjoy my life sober and am more productive that way, but a little use can boost my mood or give me something to do. This weekend my family is out of town and I'm on my own, and I almost just submitted a dispensary delivery order of just 1 vape pen and was telling myself I wouldn't be using it all day and when I ran out of that I'd restart the quitting. But if I do relapse, then stop, it probably will happen again. I'm just really feeling the cravings and want some sort of stimulation while on my own. This is the worst withdrawal I've felt all week.
