You've taken the first important step of facing up to your financial problem- well done. MABS generally seem to get positive reviews for the efforts they make in dealing with situations like this.
Some of the usual tips include:
Shopping:
Avoid using cards- deal strictly in cash.
Check Aldi/Lidl/special offers at the major multiples.
Try avoid convenience stores. If you absolutely must use them, be ruthless in your spend- no unnecessaries!
Try preparing large quantities of rice based/ pasta based / stew type dishes that will last for a few days. Freeze unused quantities. Avoid takeaways/ convenience-ready made meals. Personally, I'd suggest cutting the fortnightly wine (maybe once a month) if things are so bad but I know you've got to live a little too
For clothes/shoes- check the charity shops. You'd be surprised at the things you can pick up.
Energy & utilities:
Have you switched from ESB to other suppliers- some savings to be made.
Lower the thermostat/ switch off the lights/ wear an extra jumper to stay warm rather than turning up the heat.
Where relevant/ feasible, run applicances at night rate (make sure that you have a night rate meter installed- I think the ESB will install for free)
Your phone bills are pretty high- check the packages available.
I'd strongly second the 'get rid of the TV package' advice and would add check the deals for internet access.
Other income:
A previous poster suggested that your husband could do some childminding (tax free if under approx €15000 pa all in [with conditions]). Equally, fast food deliveries might be a possibility. Alternatively, could you rent a room in your (tax free up to approx €10000 pa)
