I'm the same, it's called addictive personality. Which is why i've not gone near Heroin.
When you do get off it, roasted Dandelion roots make a good caffeine free drink, I have it with milk and 2 sugars
Ha! Well, it's relieving to know I'm not the only one. I definitely stay away from many things, just in case I like them. I know about dandelion - I'm one of those health-nut juicers and WHOA! One time I put dandelion leaves in my juice and I was bouncing off the walls with energy - but a non-jittery energy. I never thought about them again until now! Thanks for reminding me. I didn't know I could make a little dandelion brew...
