I agree wholeheartedly with the respondents above. I would say up your nicotine level. If you look up Nicotine on Wilkipedia It states;
Nicotine's mood-altering effects are different by report: in particular it is both a stimulant and a relaxant.[31] First causing a release of glucose from the liver and epinephrine (adrenaline) from the adrenal medulla, it causes stimulation. Users report feelings of relaxation, sharpness, calmness, and alertness.[32] Like any stimulant, it may very rarely cause the often catastrophically uncomfortable neuropsychiatric effect of akathisia. By reducing the appetite and raising the metabolism, some smokers may lose weight as a consequence.[33][34]
When a cigarette is smoked, nicotine-rich blood passes from the lungs to the brain within seven seconds and immediately stimulates the release of many chemical messengers including acetylcholine, norepinephrine, epinephrine, vasopressin, arginine, dopamine, autocrine agents, and beta-endorphin.[35] This release of neurotransmitters and hormones is responsible for most of nicotine's effects. Nicotine appears to enhance concentration[36] and memory due to the increase of acetylcholine. It also appears to enhance alertness due to the increases of acetylcholine and norepinephrine. Arousal is increased by the increase of norepinephrine. Pain is reduced by the increases of acetylcholine and beta-endorphin. Anxiety is reduced by the increase of beta-endorphin. Nicotine also extends the duration of positive effects of dopamine[37] and increases sensitivity in brain reward systems.[38] Most cigarettes (in the smoke inhaled) contain 1 to 3 milligrams of nicotine.[39]
Research suggests that, when smokers wish to achieve a stimulating effect, they take short quick puffs, which produce a low level of blood nicotine.[40] This stimulates nerve transmission. When they wish to relax, they take deep puffs, which produce a high level of blood nicotine, which depresses the passage of nerve impulses, producing a mild sedative effect. At low doses, nicotine potently enhances the actions of norepinephrine and dopamine in the brain, causing a drug effect typical of those of psychostimulants. At higher doses, nicotine enhances the effect of serotonin and opiate activity, producing a calming, pain-killing effect. Nicotine is unique in comparison to most drugs, as its profile changes from stimulant to sedative/pain killer in increasing dosages and use.
It's no wonder that with your type of work you don't feel like you are as alert as you did with the amount of analogs you smoked. Analogs make you alert, and according to Wilkipedia, can also help you slow down, to sleep.
Don't give up, try different things. The best thing about e-cigs is there are so many different things you can try, all under your control. Unlike analogs.
