First and foremost, THIS! Back in the day Trustfire batteries were all we had to choose from. Battery technology has exploded (excuse the pun) since then. Trustfire batteries have always been bad for all the reasons that Topwater Elvis said. ICR batteries are no longer recommended for vaping devices. Throw those Trustfires away. Please educate yourself on what batteries to use.
IMHO, finding a flavor that you don't mind using every day is probably the toughest endeavor on anyone's vaping journey. I personally never liked tobacco flavored e-liquid, so I can't really help you with this one. If there is a vape shop that allows flavor testing, it might be worth a day's trip to try a lot of different flavors before buying.
I don't think there is a tank of any kind that allows you to drip after it has run dry. You may want to look into a Bottom Feeder mod. Also known as a "squonker". You sorta drip "upside down".
These are box mods (either mechanical or regulated) which contain a refillable juice bottle inside the mod. The body has a window that exposes the bottle that allows you to manually press to feed your e-liquid into the drip atomizer. You vape until the atomizer needs more juice and then "squonk" more juice into it. These devices use special rebuildable drip atomizers which can connect to the juice feeding system.
This is about the closest you'll find of having a "tank" that you can drip.
Sounds like you are more of a deep-lung (DL) inhaler and not a mouth-to-lung (MTL) inhaler. Most tanks are designed to be one or the other, but a few can be adjusted to do both with an air control ring or by changing the drip tip (mouthpiece) to either a small bore or large bore.
I am more of a DL inhaler, but occassionally I like to MTL. I use an original Uwell Crown clearomizer tank.
Authentic Uwell Crown Sub Ohm Tank Clearomizer . Technically it is a sub-ohm tank, but you don't have to sub-ohm with it. It has
1.2 ohm coils available for it . It is an easy top fill (4ml capacity). It has a ratcheted air control ring which allows wide open direct lung draws down to a tight mouth-to-lung draw. It has a wide bore mouthpiece, but you can always replace it with any inexpensive small bore mouthpiece if you desire. Great flavor, a lot of vapor.
I think it is the most versatile tank on the market.
Mechs are not all that simple. You can't adjust the vape easily on a mech. As the battery drains, the vape is going to drop off.
There are far more advantages to using a regulated mod over a mechanical. First, you can adjust your vapor on the fly. Lower wattage earlier in the day, higher wattage later in the day if you so desire. Regulated mods have a chipset which keeps your vape the same from the beginning of the battery until it needs to be changed. And lastly, regulated mods have safety circuitry to prevent over-discharge of the battery and protect against short circuits. You can turn the mod off when you carry it in your pocket, a very important safety practice.
Agree. Being tobacco-free for almost 7 years now, I can smell a smoker from about three feet away. Their clothes stink, their hair stinks, THEY STINK. You can't cover it up with cologne or perfume.
Agree.
I had a friend who quit smoking using this. She put the contents of an ashtry into a baby food jar along with some water. Every time she desired a cigarette, she opened the jar and took a couple of good whiffs.

Sorry for the long post but you did ask a lot of important questions. You have been given excellent information and a lot of choices to consider. Good luck.
