I'm here 
We overspent at Xmas and had plans for no spend January.
The only spend was going to be a spare freezer for stocking up so we can only food shop every fortnight rather than weekly as we overspend.
We also have set our weekly spend at £90 but know we can lower that with meal planning so that's what we've been doing.
The upside was a friend was getting rid of her freezer so we didn't pay a penny for it 
The downside of January was a new iron after mine got melted by ds,a new hoover as ours blew up ,an mot and tyres and a slow puncture emergency repair 


Plus dd broke her school boots and didn't fit in her rain coat,oh and she needed new shirts and tights for school as well as a bowling trip.
Ended up spending more than we had ever anticipated so scraped back with a plan for feb.
Did a big good shop last week and spent £150 which should do two weeks although may have to do a small salad/veg top up.
The water went up by £35 a month but the council tax will be due to go down by about £20 so give and take and we should even out and just not go anywhere to spend!
My personal plan is
1 coffee out either on a Sunday or Monday (days off)but not both
No make up or clothes purchases for me or the dc (nobody needs anything)
No buying pastries or nice breads from the reduced section (worked out I spent £10 in one week and most of it got wasted
)
No online purchases. I no longer have eBay or amazon app on my phone.
No more pootling to nearest supermarket for a look around and coming out £30 lighter with a bag of crap 
Fingers crossed
