Hi Angy... similar situation with me. I was on 1300 a day and I've been slowly upping that to see if I can hit a balance for maintenance.
All personal choice, but I don't think I'd suddenly zoom up to a particular maintenance allowance, mainly because I'm not sure what exactly that is for me now! Maybe you feel the same. How about adding an extra 200 calories to your daily allowance for the first week, then another 200 the second week, then a 100 the third week... just gradually easing your way up over the course of a month and seeing what happens to your weight. It's likely you'll continue to lose a little bit until you hit the balancing point, but hopefully it'll ease you into maintenance gently and help you find the allowance for you.
Many many congratulations on the fab weight loss, by the way, you must feel wonderful!!
