I have very bad impulse control and developed a serious justeat/deliveroo habit that had a financial impact that wasn't good.
So I deleted my accounts on those (not for the first time lol) and am also doing stuff like I set up different bank accounts I can't easily access etc.
We're not talking sendiing over massive amounts of money, I just can't be trusted with any much.
I know this is a first world problem but it was probably not good for my health. I'm not overweight at the moment but hope to lose a few lbs- and not be as broke.
I've even found ways around it, like the bank lets you/me go into being overdrawn as long as you go back into the black by the end of the day- so that's my diet-screwing treats or takeaway sorted. 
Anyone else do exotic things to try and stop their spending on something?
Did it work?
