Answer: I have similar problems, I’m user weight and need to gain weight, I measure my weight every month. And what I do is I get up in the morning drink a full cup of water (doesn’t matter if you feel like vomiting, you need to make yourself drink the whole cup) then I eat amlet and more bread because it helps you gain some weight. Then at 10-11 am I have another meal (not a lot, I just eat as much as I can) then at 12-1pm I eat some food that has meat and some veggies in it and plus a salad (it doesn’t matter what time you eat usually, you should have 1-2 hour break so the food digests) then at 2-3pm I eat some snacks (the ones without a lot calorie, too much calories makes you vomit) then at 4-5pm I have some tuna salad, then at 6-7 I eat another meal that doesn’t has too much calories because it will be hard for your stomach to digest the food. Have a walk in a fresh air. Make sure to give it some time before you go to bed, because if you sleep with a full stomach, your digestive system won’t be able to digest your food while you are laying, and it will cause you to vomit. It might be too much in the beginning, just give yourself some time to get used to this as a daily routine. Well this is all I do to gain some weight, it somewhat helps, but Im still not fit enough and I need to keep this routine. And btw whats your weight? Mine is 108 pounces (lb)
Explanation: I would strongly recommend you to drink vitamin c in every morning, (it’s really useful, and makes you get hungry fast)
