Wow, am I ever glad to read this post! I've been wondering about some of this stuff.
I couldn't say if vaping has affected Shark Week yet, since I'm only about five weeks in. However, I've noticed problems with irregularity, which I'm hoping that drinking plenty of water will flush out.
I had a bit of insomnia for the first week or two, but for the past couple of weeks, when I hit the pillow, that's it - I sleep like a brick. I was a pretty good sleeper before, but stuff like restless legs and leg cramps would interfere somewhat regularly, maybe a time or two every week. The restless legs have completely gone, and I no longer take the herbal pills for them. I also don't get leg cramps like I used to - only one bout of them in the past few weeks, which is an improvement. And I bounce out of bed at 6:30, sometimes earlier, feeling rested. I miss sleeping in on the weekends, but I'm okay with waking up at my usual time, as long as I've had a good night's sleep.
I had to cut back on my coffee intake - I used to have an extra cup after getting the kids off to school, and had to knock that off, because it was making my heart race. I thought that was weird, because I've always had that extra cup, and it's never bothered me. Now I have one in the morning and one around 2:00, and that's it - water for the rest of the day.
Since I'm still so new at this, I'm taking a wait-and-see attitude about changes that I'm going through. Some people say it takes a full year for their bodies to get back in line, especially after decades of smoking. I smoked for 30+ years before I took up vaping, so I guess I'll just be patient and see how things go with my body. I just hope the digestion issues settle down before too long - I dread going to the bathroom these days.
Too much? Sorry!
