Mounjaro fatigue

I am 75, T2D. Along with insulin, I’ve been taking Mounjaro 5mg for 18 months now. Recently I’ve been hit with fatigue which has caused me to have to stop any physical activity requiring exertion. My dose was reduced to 2.5mg weekly which is the lowest dose of the drug. It has been almost a month since my last dose. The research says that it could take a month for it to be completely out of my system. The fatigue has not gone away. I also for many years have been taking a statin, pravastatin, without any side effects. But it can also cause fatigue (even only after long-term use I wonder?). At this point I will be stopping the statin so both drugs will be out of my system and hopefully I’ll get my energy back. Has anyone else experienced this situation? Thank you
