Hi Nick,
I think my experiences come in the ‘bad’ category.
The first time I had Zometa, I was fine for 2 days, then as I parked to go to the gym, I felt all energy drain from my body in an instant. I turned around and went home to bed.
Since then, I either get this loss of energy starting 2 or 3 days after Zometa and going on for around 2 days, or I get the ‘flu-like’ symptoms which my nurse warned me about (but worse than they implied).
Let’s just say that I was originally due to get Zometa every 28 days. After I pushed back on this (because the side effects were distinctly unpleasant), this changed to every 3 months (or to be pedantic, every 3 x 28 = 84 days).
At least I know to anticipate feeling horrible then, so I plan accordingly. My next Zometa is due next week, so I am not planning anything more strenuous than reading and watching TV a couple of days later, as I probably won’t feel able to do much.
