I found, at the beginning, I was all over the place emotionally. There is, of course, the immense sense of relief, then comes guilt -- followed by "what have I done" !
I took great delight in accounting for every penny and paying my grocery shop in cash (something I hadn't done for years). You will soon learn the worth of "real" money when dealing in cash --- it is far harder to squander a real tenner than it was to flash the magic plastic !
One little tip -- don't carry cash around with you -- only when you know you are going to spend it -- it is amazing how little sweets here, a magazine there, and so on, add up.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
