I want to hear honest reviews about weight loss injections.

My stomach is naturally very weak and sensitive, and since I'm having trouble losing weight, I'm looking into weight loss injections. I looked through community reviews, and while they suppress appetite really well, quite a few people mentioned that they struggled with daily life due to nausea, vomiting, and headaches. My digestive system is already weak, so I'm suddenly terrified that getting these injections might just harm my body due to side effects. I'm starting this to lose weight healthily, but I'm hesitant to go get a prescription because I'm worried it might just ruin my condition instead. Has anyone with a weak stomach tried weight loss injections? I'd like to hear honestly how you endured the nausea and lethargy during the initial adjustment period, and whether it interfered with your daily life.
