Yes, I’ve had/got it. Had two major episodes over the last ten years or so, lungs, kidneys and eyes took the brunt. My energy levels were way low but the main thing for me was the eyes, couldn’t go out in daylight and its left me with Posterior Vitreous Detachment, kind of like a detached retina but vision has returned to an acceptable level. I was treated with steroids, its a hefty dose to begin with but that reduces during the treatment,and for me it was worth it. I didn’t put on weight or for that matter suffer any significant side effects (that I’m aware of). Don’t loose heart, there is light at the end of the tunnel, I’m out on my bike every couple of days or so. Be strong.
