Anxiety
"I was given a sample pack, but it has the opposite effects for me, as I had an increase in fear of danger, and worrying, I was extremely focused, and unable to sleep. My doctor has had me test a few anti anxiety meds Ativan, antidepressants, and the only one that works for me is Xanax at a low dose.
I would make sure you consult your doctor first on this one."
