It definitely does work in terms of curbing your appetite but remember you must be disciplined. I had morning headaches every day for the first 2-3 weeks that stopped with paracetamol. The headaches eventually stopped. Remember you MUST inject on a different side each week alternating left with right. I’d suggest writing down on the box which side you injected on. The Wegovy needle comes with 2 protective caps. You peel the first one off and then twist off the second cap. Remember to hold the injection for a count of 6 after you have injected and the spinner has stopped spinning. It seems daunting at first, but the instructions have step by step pictures to guide you through the injecting process. It says you can inject on your thigh or stomach. I always inject stomach because I’ve got a good layer of fat there lol.
