Again sjw, having re-read my post, it may be read as me having a go at you - that's not my intention, I was merely trying to offer some advice. And, at the end of the day, who can blame you for trying to squeeze one last "luxury" out before you go into an IVA?
The thing I think I will find out from the IVA is that you appreciate things which you took for granted before. For example, I will probably get myself one bottle of wine (£3-£5) from the supermarket to have at a weekend, and maybe a couple of cans of lager, and that will be my "luxury", and I will enjoy them. Before, I would have thought nothing of spending £50 on alcohol and having nothing to show for it, apart from a sore head! Whatever your luxury may be (a box of choccys, a bunch of flowers, etc), I think they will be appreciated more.
