Tips on how to get enough Calories in a Day

Hello everyone, first time posting here. I just wanted some tips or advice from those on GLP1s who have had trouble eating enough in a day. I'm currently on 1MG weekly and sometimes it feels like I cant get much down. I'm very overweight and new to all this, currently looking for a dietician/nutritionist, but until then just hoping to get some advice. It all feels overwhelming and complicated with TDEEs and worrying about malnutrition. I'm around 400lbs so in theory I need a ton of calories to live but I can barely get 2000. Any tips will help or next week when I see my doc again I might have to ask for a lower dose. Side effects are rough but manageable, its mainly just making sure I eat enough when I always feel full or dont feel like eating. Thanks in advance!
