anything that 'gives' you energy is unsafe, cuz obviously its gonna make ur body work in overdrive. thers chances that u can have cardiac arrest or something
anything that makes u 'feel' more energetic is unsafe, cuz u'll feel all good, and ur body won't be able to make u stop when its had enough, and u may also have a heart attack. frankly tho, if you work 14 hours a day, and say u take 1 hr to go and come back from work, that gives you 8 hours to sleep
Sleep is your magic weapon, seriously, NOTHING makes up for it. plus if you force yourself to go for a small jog, u'll like collapse when u get home, so you won't waste time waiting in bed while u try to fall asleep. just increase the distance of ur jogs little by little, in a few months, your body should become much more accustomed to jogging, it'll become more efficient, u'll feel more energetic all without substances.
