depression
"This medicine increased my mood within a matter of days. However, when I increased my dosage from 10 mg to 20 mg in the start pack, I got violently sick, nausea then extreme vomiting with a headache. Worse than any hangover that I have ever had. The problems lasted for 2 days and eventually diminished to a headache. When I started taking the medication I notice that a numbness in my arms and shoulders at night and stiff joints in the morning. When I stopped the medicine the muscle stiffness and joints decreased. I was on the medicine for almost a month and still have the stiff joints and muscle aches.  I was an endurance athlete and this type of pain was different."
