I think I may also be dopamine deficient. I have no willpower and have extreme trouble sustaining attention. For the braverman I took did the first 34 questions then realized I wasn't even half way and abandoned it. I have no ambition, no energy, no interests. Always irritable, never feel like socializing, don't have anything to say, lack of novel thoughts, everything is just dull and boring. 
Does this sound like dopamine deficiency?
I just sort of seep in my own boredom until it gets unbearable, and then I just keep on going on.
And when I take dexedrine, it's like I'm normal. I take interest in things, don't feel this overwhelming boredom and this need to do something about it. I am content doing whatever I am doing, feel like socializing. Could be the normal effects of amphetamine, but it's such a pronounced change for me I feel that maybe this dopamine is really behind all of this. 
guyledouche, how are you feeling now?  If things are the same, here is an alternative to consider:  maybe you are suffering from plain old depression, perhaps with a component of anxiety.  Below is that dopamine list.  Aside from maybe the first four, the rest of it sounds like a "you may be depressed if" table.  I'd recommend that you talk to a doctor about it and see if an SSRI would help.  Aside from that, I would try the following:  Lots of exercise, spend some time outdoors, and quit drinking and smoking weed if you use either of them.  If you do these for a year, you'll feel like a new man.
