Sleepless; Insomnia nights, cold feet and weird dreams?
Except for cold feet, I had exactly that. For a while. One thing to try is lower nic levels in the evenings. I use my highest in the morning (for that "first cig of the day" stuff). Switch down to my moderate level for most of the day then down to my lowest when I do the "fall on the couch and watch some TV before bed" thing.
Nicotine is a stimulant like caffeine is so, yeah, it can easily keep you awake nights. I remember when I smoked, I used to smoke more (often much more) times I needed to stay awake and alert.
The weird dreams thing... who knows where that comes from. I had it and I've read bunches of posts here of people discussing having it. But, remember, cigs are known to have over 4,000 (!) chemicals, over 50 of which are known to cause cancer. It's not just nicotine in there. So you've quit 3,999 chemicals. Could we ever sort out which one does what? I doubt it (least not until Star Trek and Dr. McCoy come along

).
But it went away over time for me. I think I'm dreaming these days. I sleep so much better and so much deeper, it's hard to tell. I barely experience "time passing" I sleep so deeply now. Sometimes, it's like I lay down and,
click, somebody turns the sun on and it's time to get up. I don't think I've slept that deep since I was in college.
Still, yeah, the dreams were freaky for a while. Super realistic and... tragic? They weren't quite "nightmares" so much as just... tragic. Bad stuff happening. Often very goofy bad stuff. Bad stuff that made no sense but which was quite seriously bad in the dream.
...quitting analogs was easy because of e-cig, quitting e-cig WILL NOT be as easy...probably laughable because I will fail...
So what?
Seriously, what's the worst case? You'd be stuck with a nicotine addiction. The one you already had. But you will have dumped all the cancer causing, health destroying, life shortening chemicals.
While nicotine is highly addictive, it's not terribly bad for your health (certainly not compared to all the cancer causing crap in cigs). I mean, it's not
ideal to have a nic addiction but it's not a substance known for causing lung cancer and such. It's not the nicotine in cigs that's killing everybody, it's the other stuff.
My nic addiction is pretty powerful. I may never quit nicotine. But I
am drastically reducing my chances of developing all the other horrific things cigs cause. Yeah, I smoked for a long time so that damage is done. But I'm not doing any more damage. Which is certainly better.
So if your goal over the long term is to quit nicotine entirely, good for you. Go for it.
Eventually. Don't pile on the pressure. Be happy that you're coming up on one month with no "analogs" at all. That's pretty damn good eh?
You've quit 3,999 chemicals, worry about quitting number 4,000 later.
