damn. ive never IVed anything, but ive come close to doing it. i was always very wary of the addiction potential with opiates, although i almost got addicted to those, thanks to a very large supply of oxycodone i found. 600mg in one prescription... holy shit i was in heaven for a while. ultimately what happened was i recognized the beginnings of an addiction but was helpless against it. what ultimately made me quit them was the insane increase in tolerance i experienced. within a few weeks of starting on oxy and hydro, my tolerance was so high that i couldnt even feel 120mg of oxy. hydrocodone was always much more euphoric for me, but the oxy was available. ultimately i just stopped because of tolerance, havent touched any opiates in 3 months or so. adderall is a godsend for me, it has never been addictive, but it satisfies any cravings i may get without making me high. because i cant get high from it, no matter how much i do, it isnt really addictive for me. i find if i take more than 60mg, i just feel crappier and crappier. another interesting thing about it is that i dont seem to build much of a tolerance to it past 40mg. however, as i stated before, weed is the most addictive drug for me. i crave that shit all the time when i dont have it. i recently stopped smoking it for a week or two because all my guys were dry, and i just got some more yesterday. i felt like a little kid in a candy store when i saw those luscious little nugs, and i payed more than i normally would for it i was craving it so badly. normally i will NEVER do that, but the cravings i had been getting were so intense it was ridiculous. it was all i could think about 24/7 for a few weeks, and i finally got some, and god was it the longest 4 hours waiting to smoke it until everyone else went to bed last night. that shit is the most psychologically addictive thing i have ever come across.
