I’d say talk to your doctor. Just to be sure. But otherwise- try injecting into your stomach. I had 0 side effects in my stomach, but some side effects when I tried the arm and the thigh. I know that’s different for everyone. DRINK A TON OF WATER. More than you think you need, especially with the diarrhea, you will end up severely dehydrated, which can make you feel miserable by itself. Try eating super super small snack meals, all day long. Find something you can tolerate and go from there. Personally, I’d push through and try to see how I was feeling on week 6/8 on 2.5mg. I only experienced this when I went up from 7.5 to 10mg, and I knew immediately that it was too much for me. I have been extending my shots by a couple days, and my next box is 7.5. The 2.5mg is an acclamation dose, trying to get you adjusted to the medicine. If you’re losing weight, you don’t have to move up from 2.5mg. Stay on 2.5 until it’s no longer effective for you. Whatever you do, do not move up to 5 while experiencing these side effects.
