My biggest problem too, according to the doctor, is when I binge eat, I binge eat sugars and sweets and things like "sour straps", because I love the taste... I will try dieting, but then randomly crave the sugars and just eat and eat and eat sugars, and I've battled it for years.
So the doctor seemed to think an "oral inhalation" of the juice would work for me, as it gives me the flavours, and would "trick" my brain into thinking I've got what I've craved.
I'm looking for a unit that does NOT resemble a cigarette, as I don't want the hassle of people in my family having a go at me for "taking up smoking again when I know what it does to me".... as my dad said last time I caved and had a smoke (ended up with a pounding migraine and threw up)....
And while I know colour isn't an important factor, I am a colour ....., lol. Bright, stimulating colours tend to be something my brain somehow finds it easier to cope with, than sterile metals, or weird black or white things that look like the .... end of a pen (I've always been an absolute shocker for chewing on the ends of pens, I had to stop using the plain white and black cased ones, only can now use the see through ones to remind my brain that there is ink in there, otherwise I demolish them and end up exploded the ink cartridges..... Yep... I gots the mental issues... >_<)
I've looked into a lot of flavours, there are many I would love to try..... but I get the idea that if the thing is complicated to refill with flavour, I'll wind up with the poops and just not end up using it.
