I just heard about this and FREAKED!!! I hate seizures! They are frightening to have and hard to watch. I'm glad Scott wasn't travelling alone. I'm sure he is feeling better now, especially since he later made it to Miami and everything was fine with the show.
Seizures can be caused by all sorts of things, but it doesn't surprise me to hear this immediately being blamed on drug abuse. Sometimes, the medicine prescribed for a condition such as bi-polar disorder, etc., can cause seizures. Also, changing from one prescribed medication to another or forgetting to take a couple doses can cause a seizure. Although the experience of a seizure is traumatic, after the initial shock wears off, one feels much better. Side effects don't usually last very long. I'm sure Scott will see his doctor to take care of any health concerns. I just wish him the very best!!!
