Depression
"Effective for depression and fatigue. 
Causes me to have energy, to need much less sleep, euthymic mood.
Sometimes euphoric mood, feel more outgoing, have increased libido, and feel very confident.
Negative side effects are hostility, being too assertive/pestering people/belaboring a point/arguing, going too far, some impulsive behavior.
I also get fearful of things I&#039;m not normally afraid of. Fear, not anxiety. Can&#039;t drive on the busy interstate now because I overreact when trucks pass me -- it jangles my nerves. Also can&#039;t go on rides at an amusement park or go up in a tall building. Physically afraid.
Also causes restless legs at night -- an urge to shake out my legs. 
Causes dehydration/muscle cramps. &quot;NUUN&quot; electrolyte drink helps."
