KLM Howdy and Welcome, Flamingo's link by bghouse, list is all inclusive, give it a read.
I got to do this one in two stages...I'd started rolling my own about a year ago with "all organic" tobacco, so basically it didn't have all those chemicals that are added to ciggies to make them more addictive, the formaldehyde, etc and 24 hours in a Sunday afternoon I was irritable, (I'm pretty even keeled unless I need to eat and it's been 8 hours or more) headache, GI issues, body aches, general malaise and creepy crawly I don't feel good in my own skin feeling.
OMG this is withdrawl! seen it plenty of times, and kind of was mad at cigarette companies...but I took to the bed for the rest of the Sunday and felt a tad better in the morning with some good food and hydration and Alieve. It took a few days but it cleared out within 3 to 4 and back to smoking ciggies. I had a little bit of one when we started vaping May 30 but really nothing like the first time, quitting the store bought ciggies.
This too shall pass.
Vaping has some side effects for some folks, there's fluid shifts, be aware of your hydration and read that list Flamingo reposted of bghouse's.
good luck and Congrats on quitting!!!
