Yes it is, for sure. I told a nurse at a sleep study that that was my dose. She mentioned she took half a 100mg pill once and stayed up for over 24 hours straight. For me it was barely enough to stay awake through a normal day. It took those 4 years and more to find enough of the root causes to not need to be on it anymore.
200 mg/​day is a pretty high dose (at least for me)
