Dexmethylphenidate aka Focalin made me very, very spendy. I didn't even realize the connection at first. Methylphenidate never had that effect at all. I was surprised to find that known side effects of some dopamine agonists (used to treat Parkinson's disease) include compulsive gambling, shopping, and obsession with sex. Not sure exactly where I'm going with this, but maybe extend yourself some grace and compassion because it really might not be a matter of will power. Frickin dopamine. I swear.
