Not super discrete, no. But, I think you can find something you'll like. If you are brave enough to use bathrooms a zelos/N2 tank will do the job. Though, I might consider (especially as you are transitioning) buying some nic lozenges and/or nic gum for during work, if you are working that long of a shift without breaks, to tide you over while you are getting adjusted. 9 hours without nicotine while doing cig withdrawal sort of makes for relapse, IMO. I still carry nic lozenges for periods of time I know I may not be able to vape (e.g. flying and whatnot). I see no harm in it, and I don't use them enough for it really to be costly. Because yeah, waiting 9 hours to vape and having your equipment pitch a fit is just not pleasant, especially after a long, stressful day. The good news is vape equipment has come Very Far, so I think you'll have less issues with unreliability. The N2 tank is pretty easygoing, as long as you close off airholes in transit, or don't overfill, it's not a leaky tank and it's easy to maintain. Given your desires, I might recommend a passthrough internal battery (like the zelos) and a bigger mod for at home (the steampunk can be purchased for about $30 and possibly less with upcoming sales as its older brother the Tesla Punk 220 is coming out). That way, you'll have a backup if anything happens to your equipment, and maybe going for an N2 and a MTL RTA clone (again, we are talking 10--20 dollars on that) might give you some nice variations in your vape, and it's good to have backups AND to switch up flavors if you want, during times you aren't working.
Best of luck, I know how easy it is to slip back, which is why I pretty much have a No Cigarette Rule Ever right now, I know one would possibly taste good/bad depending, but I am always wary of the One Cigarette that will Hook me back Into Smoking, in general. It's worked out well for me that way....
I haven't tried the C-cell coils yet but I ordered a tank yesterday that fits them and some coils, I've been meaning to try them but I haven't been a fan of the Ego Mega, mine whistled and it drove the husband crazy, but yesterday someone pointed me to another tank that fits them, so I am excited to try them, I have heard good things! BTW, my Ego One Mega experience was not typical, a lot of folks love them....

Glad you are returning to vaping!
