just want to add regarding FAS course. I did one before, 1 year ago, maybe they pay a bit more now, but back then it was €180 per week, so there not a chance it could be €400/day
Plus just to mention, i earn €20K i have a loan repayment €160pm, i'm foreigner and support my family back in my county which costs me €200pm then my rent €400pm, and all this health insurance, gym and plus somehow i do manage to go out, buy outfits and enjoy my life to the fullest..
I gess you just have to work out a budget and live by it.....
If you're only getting €400/week, then maybe you should consider giving up work completely. Find out what your options are at your social welfare office. Might even be able to get your rent paid.
A bloke in the pub told me yesterday that he gets €400/day doing a FÁS course. Maybe you could find out more about this as well.
