Congratulations on making the switch! I do find the vapor "different" than smoke, I've actually come to like it better, as for the flavor tasting like a fog machine ... chances are that's because of the fact that fog machines use glycerine or glycol mixed with water in order to make fog, what you are vaping is probably PG (Propylene
Glycol) or VG (Vegetable
Glycerine), ie pretty much the same thing as a fog machine.
It will take a few weeks for your tastebuds to come alive again, when I first started I could barely taste the flavorings in the juices I had, I thought something was wrong... turns out it was me. Almost two months later and some of the juices have TOO much flavor

, it's going to take some time for your sense of taste to heal.
As for nicotine levels, I'd suggest getting small samples of different nic levels and finding out for yourself what is too much or too little, it varies too much from person to person. If you find yourself craving ciggys really bad even through you are vaping a lot, up the nic level a touch or two... if you are having headaches after a vaping session or generally not feeling well, lower your nic levels.
I started with 24mg juice, which was okay for me, it worked good while I had it, I bought some 18mg juice and found it easier to vape, then when my DIY stuff arrived I made myself some 12mg juice, EVEN BETTER for me, I think this is my sweet spot. I ordered some 36mg juices for my friend (which she LOVES and says it's way better than the 24mg I gave her when she started), anyway, I tried some of this 36mg juice and it damn near blew the back of my head off. WAY too strong for me personally. The weird part is, I was a pack a day+ cigar smoker (and I inhaled), she smoked maybe a half a pack of extra lights / day... 12mg is my sweet spot and 36mg is hers, and she vapes almost as much as I do. Nic levels vary too much from person to person to suggest anything. (*Although I would suggest starting with 24mg or lower and not going to 36 right off the bat*)
The best advice I can give you is STICK with it, there is some fiddling involved in vaping, don't give up, stay strong and you can kick the cigarette habit and get your nicotine through vaping which is MUCH healthier.
