That is something I would do. In fact, by preference I would spend a day coding it up instead of two hours in aggregate manually bookkeeping. "Flow" vs "Ugh"!

I should note that the role nicotine lozenges are taking here is not primarily as a training reward, like giving the rat electronically stimulated orgasms when it presses the lever. Nicotine isn't particularly strong in that role compared to alternatives (such as abusing ritalin), at least when it is not administered by a massive hit straight into the brain via the lungs. No, the particular potency of nicotine is that it potentates the formation of habits for activities undertaken while under the influence by means more fundamental than a 'mere' stimulus-reward mechanism. Habits that are found to be harder to extinct than an impulse to take a drug. This is what makes smoking so notoriously hard to quit even with patches and makes the use of fake cigarettes to suck on useful.

In a different thread I've been discussing nootropics that enhance learning via the acetylcholine system. Half of those acetylcholine receptors are called nAChRs (Nicotinic acetylcholine receptors). This is not a coincidence.

The other fascinating (to me) fact regarding nicotine is that it has the opposite effect on the sensitivity of the brain's reward mechanism than other stimulatory drugs of abuse. Where abusing meth, cocaine or coffee will make all rewards you experience in life less salient when you stop medicating, the reverse occurs with nicotine. The systems get downregulated but that mechanism is itself countered with the addition of more receptors leaving a net boost. This means that if you stop using nicotine food starts to taste really good (and you may gain weight!)
