as well as looking at your debt, look at your current spending. My personal favourite way of checking off where my money 'disappears' to is a notebook / money diary.
as soon as a cent leaves your pocket note it down (playing catch up later that day doesn't work, its amazinf how easily I can forget a bottle of water, petrol, magazine...). It can provide a wake up call for where you are spending unneccessary money. You might feel silly for a day or 2, wandering around with a notebook, but if you have one a PDA is a useful, or even post-its. Check your progress at the end of the week and see if there is a trend... does a night out have you spending excessively on energy drinks / breakfast rolls / chocolate.... Do you treat yourself to something on payday, even when it isn't payday...
you may find another hundred Euros or so that you can use against your debt.
Personally I found Alvin halls books 'your money or your life' and 'money for life' very good for giving you the basics of getting out of debt. If you are close to dublin, I've noticed that Chapters on abbey st frequently have 1 or other second hand. If it helps to encourage you at one point he had maxed about 30 credit cards at the one time (he's american, we'd be bankrupted with the tax here!), so he's been there and does know the pain.
One other item you might want to consider is if you have Eu3000 to pay off against debt, do you want to reduce the number of debts... would it help your frame of mind to only have fewer outstanding debts? so would you prefer to pay off overdraft, visa and most of your MNBA and only need to concern yourself with CU and BOI. paying off highest interest first is a good idea, but sometimes you may find that only have 2 debts instead of decreasing balances on 5 may help you focus. Its a personal preference I have, others will disagree.
Good luck to you
