Hello LivDee, I had a gastric sleeve 13 years ago, and yes I tested the water on what I could eat or not eat. I lost nearly 50kg and then put half back on simply by drinking alcohol. I stopped drinking and went on to have a baby who is healthy and now nearly 8. I can tell you that even though you stomach may stretch it wont stretch to what it was before and I am still now restricted as to the amount I can eat. In most cases an entree size meal. It is also dependant on a few factors, the more protien in a meal the less I can eat, there are also foods i dont digest well. It is really important to always chew your food really well. I was 142kg when I had the sleeve done and today sit at 114.9kg. I had made it to 92kg but when I added stupid calories like alcohol and sugar it will catch up and you can still put on weight. But the good thing is you can continue to loose weight but it does get a little harder with cravings when you expand you tummy. The other thing if you haven't adressed it and I say this everyone starting this journey, look at your relationship with food and recognise always why and what you put in you mouth. My relationship with food has changed but it has been a journey and not the prettiest one but I can recognise and analyse and make change more easily now than before. I still have a way to go and will be going in for a sasi and to get my hernia fixed, but my headspace is even better today. I guess in otherwords take it easy try and follow what the Team tells you and be kind. Each day is a new adventure and take this as a jouney of empowerment and discovery about you. This really will change you so don't be scared to seek counselling if you need to as new situations will come forth that you have not dealt with and this can make you want take in the wrong things. As for after op eating follow the stages while your stomach is healing if you eat too much it can damage it. Its also great you are recognising what you feel is different and asking questions because that is how you get to know more about the new you. Keep going you got this. Best regards
