Reactions and side effects are dependent on the person. I’m healthy so I don’t typically take medications but this was my experience on Strattera, which you’re supposed to take with food. That warning was no joke. I had to take it with a meal, because I’d risk feeling queasy with only a snack. But at low doses, it was fine. Very manageable.
As my dose was increased, the nausea started becoming constant. I couldn’t do anything to relieve it. At one point I was at a restaurant and had to go throw up in the restroom. After that I decided to stop taking Strattera, because the nausea made for a miserable experience and was not worth it at all. I was instantly better once I stopped.
