I think it started off because of a long weekend I had once, then the next weekend I ordered it a day sooner to ensure it arrived by the weekend meaning it came on the thursday. But its always too much.
I don't need 500mg! I keep thinking I like the safety net of having too much, but it just means I take stupidly high doses without really thinking about it and going to bed ridiculously early because I think its later than it is. I was in bed for 10pm last night, thats early even for a work night.
I always over-estimate my tolerance too, thinking Ill need like 30mg doses, when actually 20mg doses will suffice. Lesson learnt.
Though in fairness this week I only ordered 500mg because I was drunk, then my card got declined but I didn't see that until the next day at work so it was just easier to click "reorder" when on my phone.
