Hi, I really need advice, tips, anything to help me gain weight. I’m 5’7 and my current weight is 89 lbs. I’m aware that’s I’m extremely underweight, and I’m tired of it. It’s getting to point were I’m aware it affecting me, for example, I’m always tired, daily headaches, dizziness and low iron. I have tried bulk smoothies (800+ calories ones), they did work however I just can’t get myself to drink it all without vomiting right after. I have a small appetite. I just want to gain weight so any suggestions, recommendations or advice will be appreciated!!
