Chiming in on side effects... I've been vaping for approx. two months. After the first week, I quit analogs completely, which I was quite excited about. What I noticed initially was the typical, mild dry throat. My husband then made an e-liquid for me that consisted of a mix of PG and VG (together with nicotine and flavor)...which was less irritating to me than the PG liquid I ordered with my e-cig. Also, for the first week or so I would sometimes experience a moderate headache in the afternoon.
Looking back, I believe the headache might have been caffeine withdrawal. Due to the dry throat, combined with no longer drinking a strong flavored liquid to drown out the taste of analogs, I found I was often drinking iced water as opposed to coffee or tea. Another effect I associated with smoking cessation was skin irritation. That has now subsided completely, which may have been helped with the significant water intake, flushing toxins, etc. BP has also dropped. It was typically 140/90...now around 128/82...which was a nice surprise!
The tea bag as cart filling intrigues me...I plan to try that!
