How to take advantage of the withdrawal symptoms of antidopaminergics?
Short answer
Taking dopamine antagonists leads to serious side effects, and stopping taking them leads to other, equally nasty side effects. None of them include happiness or feeling energized.
Background
So basically, based on our discussion in the comments, I think you are after the following:

Is it viable to use a drug originally meant to suppress dopamine
transmission to induce tolerance and thus increase dopaminergic
effects to enhance dopaminergic transmission to enhance mood and happiness after stopping the drug to reap the benefits of long-term 'withdrawal' symptoms?

First off, drugs targeting the dopaminergic (DA) system are associated with serious negative side effects. To step into the class where you are after, the classical anti-psychotics that inhibit DA signaling are associated with the following side effects (taken from the page on haloperidol from WebMD):

dizziness

lightheadedness

drowsiness

difficulty urinating

sleep disturbances

headache

anxiety

in rare cases sometimes permanent tardive dyskinesia, a nasty side effect marked by stiff, jerky movements of the face and body, muscle twitches, eye blinking, tongue thrusting, uncontrollable shaking, or arm waving.

rarely neuroleptic malignant syndrome occurs including: fever, muscle stiffness or muscle pain or muscle weakness, tiredness, confusion, sweating, fast/irregular heartbeat, dark urine, and kidney problems.

And the list goes on, and on, and on (see also Drugs.com)

Long term-use may lead to drug-induced Parkinsonism, which is actually the second most common cause of Pakinsonism in older people, after Parkinson's syndrome (Thanvi &amp; Treadwell, 2009.


Now fast forward to your withdrawal state that should make you happy, as dopamine transmission may indeed be exacerbated. The tolerance to haloperidol comes, at least in part, because D2 transmission is enhanced in the striatum in the brain (Ginovart et al., 2009)0. This leads to the dreaded tardive dyskinesia.
Abrupt stopping haloperidol intake after chronic use results in side-effects on their own in psychotic patients (apart from re-inducing psychotic states), namely (Bronson, 1993):

nausea and vomiting
sweating
as well as a relapse into psychosis characterized by anxiety, depression and internal chaos. Interestingly, the authors conclude that the so-called relapse into psychosis may actually be caused by withdrawal instead of the underlying disease state .

In all, happiness doesn't seem part of the deal of acute withdrawal from a well-investigated dopamine antagonist, unfortunately. Taking them is a pain, and stopping them abruptly is also not a pleasant thing to do either. When you slowly decrease dosage the withdrawal side effects will be less severe.
