I've been taking addy for a month daily 20mg xr, the first time I abused it for a test was last week when I did 80mg in 24 hours. I went to the doctors to refill my script, and I told him that the addy stops working at around 5-6pm if I take it at 8am, hoping to get a 5 or 10mg ir booster. However, the doctor just came in, and in 5 minutes he just gave me the same 20mg script, without even asking me anything about how its working, and I didn't want to push it cuz I got drug tested and I know I will show positive for weed and might not have any amphetamine cuz I skipped 2 days to get back to my schedule after the 80mg abuse day. Ive been taking it this week and i barely feel anything. IDK if their is a way to lower my tolerance besides skipping days, ive read about magnesium and using tums, but im not sure how effective these methods are.
