I was taking Antimalarial medication (Meflequine?) due to a deployment. You take it once a week. The floor would suddenly feel like it shifted 90 degrees. After a moment it would settle down. Also; there was a feeling of “turbulence a few hours after taking it, but it didn’t last beyond the rest of the day. At first I thought it was Earth tremors.
Don’t get me started on what people who took Ambien went through!
Why do people want this crap when it’s not absolutely necessary (like to prevent malaria)?
No clue. I blame docs and druf companies. My best friend needed to take a med to treat his high blood pressure. A side effect was that he would easily become wildly enraged (I saw it, it wasn't pretty) so the doc prescribed some happy pills. Happy pills had some sort of side effect, so the doc prescribed something else. And so on.
My friends bathroom looks like a pharmacy, now. I'd expect it if he was in his 70s or 80s...but the guy isn't even 40 yet. And he's not willing to try another doc, or a different set of meds.
