comparable stimulant to nicotine

i have been smoking nicotine since a ripe young age; and have been a heavy user for 8+ years. i recently made a new years resolution with my girlfriend to stop vaping and i switched over to zyns; which worked well for me however i wasn't a fan of the flavor and they started to give my gums issues. i recently made the hard choice to stop as a whole and have been killing like 2 packs of altoids a week. i work at a desk job; and nicotine was a great help throughout the day. does anyone know or or reccomend any similar stimulants with safer(ish) delivery methods that i may be able to use in the workplace? i've looked into things like neurogum and such but am unsure.
