Nicotine increases reward sensitivity:

http://www.jneurosci...7/4681.full.pdfJust research on google, lots of studies on nicotine. There are some drawbacks. But for me the positives >> negatives.
Another one to look is Catuaba, I never used it but will... Catuaba is very used in South America. I think this is a promissing natural. I read from a member that it increases dopamine sensitivity but did not found any study. This is a good one:

For a releasing agent you can use methylphenidate (MPH) or dextroamphetamine (DEX). I like both together, a low dose (5-10mg) of Ritalin combined with DEX (10-15mg) increases motivation, confidence, mood, self-control (executive function) and MPH prevents amphetamine toxicity. Many studies indicates that amphetamine increases sensitivity to dopamine. Maybe tolerance is due other factors like hormonal imbalances, nutrition, sleep...
Avoid cholinergics, serotonergics and dopamine agonists. Substances like Piracetam and high dose choline makes me suicidal and violent. Rhodiola (increases serotonin) makes me super-violent, super-depressed and suicidal. Dopamine agonists makes me lethargic and cancel the stimulant effects of MPH or DEX. It can cause DAWS (search this). Maybe a partial DA-agonist like Hydergine is a good option. Hydergine is interesting (powerfull anti-oxidant, reduces prolactin, anti-anhedonic, neuroprotective and slight psychedelic), but use very low dose because is anti-adrenergic (50-200 mcg) and fuction as a dopamine antagonist when used with DA releasers.
Maybe a good combo is l-phenylalanine daily (low dose 250mg to increase dopamine production), nicotine patch (low dose 1/24 of 21mg to regulate dopamine system), l-theanine (100mg - neuroprotective and relaxing, maybe upregulate dopamine), Catuaba (dopaminergic with speculated opioid activity) B-complex (maybe very low dose sulbutiamine 50 mg - you dont need much, just smell your urine after a normal dose of Arcalion 200mg), zinc, magnesium, anti-oxidants (found in yerba-mate, dark chocolate, coffee, fruits, vegetables...), good nutrition (Google "Ray Peat") a powerfull stimulant (MPH or DEX), and good downers (Wine, Marijuana, exercise, sex...)
Here we have a "NZT Lite"? I'm justing feeling invencible after a long depression using some of those substances. No, it's not mania... or? I hope not.
