Hello all,
First time post, long time lurker, long term member from opiophile

so if anyone could help me it would be appreciated greatly! !
Okay here goes, been on long term maintenance with sub for a previous pill habit, haven't touched "actual" pills in over 5 years. Have occasionally used Ritalin but it's been at least 2 years since the last time. So a friend owed me money and after months of not paying me back I finally just told them to trade me something they thought was a fair equal value. I came home last weekend to find they had left me (2) 27mg generic Concertas? (3) 15mg adderall xr and (4) 30th adderall xr, so I have never taken any of these before and have no idea if it was a fair trade (he owed me $30). So now I have these and would like to try them but I am nervous as I have never taken addys before. I would say that I probably am not hugely affected by regular stimulants, I have issues with energy and focus so I typically take caffeine pills and (bronkaid/ephedrine) every 4 hours every day. Don't know how that would compare stimu wise but wanted to add that in there. I have spent HOURS reading about this and still can't find what I would consider a solid answer, when I have done rits in the past they were always ir and I would do 5-10mg intranasally about every 4-5 hours, but like I said it's been years and even when I did do them it was never for long periods, a couple days here and there maybe 3 days a month. I am really trying to avoid any panic attack like feelings and not looking to go on a Binger nor looking for a "euphoric" feeling, just hoping to get the same affects as I did from rit, focus and and actually being able to get some things finished.
Thank you for any advice or insight you can give!!!
