Struggling with Side effects

Hi, I’m 9 weeks into Mounjaro, 4 weeks 2.5mg then titrated up to 5mg, had awful side effects so I’ve been taking a lower dose again. I get side effects up to 3 days after the jabs — headaches, sickness, diarrhea. Once I feel better the food noise is back. I think I’m going to have to stay at 2.5mg for a while. Did anyone else experience this? When did the symptoms get better? I’ve plateaued for the past few weeks. Thanks!
