YAY!
Go for it - well done on coming this far! I too was terrified at the start... Take it slow, follow the two stage rules to the letter, and you will be fine. Do a bit of weighing of bread and cheese to start with so you get a feel for portion sizes, but try to stop it as soon as you can. Try not to weigh every day either (it took me ages to let go!). Should you keep losing and you get worried about that in the longer term, then come back for more advice, but don't start adding random off-plan treats 'because you can'
Remember also that you are *still* on a restricted eating plan. And a celebration meal really should be classified as a 'normal meal but no seconds' with a drink if you like. Just ONE MEAL, not a whole day. But you *can* accept friends invitations and go for a meal out without stressing, as long as it's only once a week. What you may well find is that you make healthier choices now anyway - for example I tend to gravitate towards fish and salads and away from pork belly ;-) or creamy sauces, which would have been unheard of in my 'before' existence.
Remember the one PP day but try not to put in extra PPs to make up for bad behaviour - a sure recipe for disaster.
You need to plan your week - I used to write them out on a weekly planner making sure there was one carb day, one celebration and one PP (make that the same day always), and 4 PVs. I successfully worked my way through the Christmas period in Conso, really not sure now how I managed that!
