I've been on 4 weeks and taken 3 injections of 1.5 mg. I have not felt nauseous or sick or anything until 2 days ago I'm pretty sure I inflicted at all myself by having two cups of coffee and taking a handful of supplements without making time to eat I threw up twice and after that immediately I started having burning irritation sensation throughout my intestines and heartburn at the same time every time I eat now it's kind of like a dull pain. Its definitely new and not something I have ever felt before has anybody experienced anything like this? Today was my injection day and I did not take my fourth dose I sent in a message to the provider have not heard back yet. It's like a burning irritating feeling in my intestines and heartburn feeling upon eating or drinking.
