I pick up my Diazepam, Codeine, Tramadol and Ritalin every day at the local pharmacy except for Fridays when I get 3 days worth. Daily pickups keeps my use under control, otherwise I would binge until my meds are gone.

I made this decision together with my GP (read: was forced) because I had a pretty hefty Ritalin addiction at one time, say using 250 mg insufflated daily when I got 50 mg prescribed. Kicking the Ritalin was both physically and psychologically very hard since I fiended that stuff like someone would fiend coke. I took me 8 days of pure hell (restless leg syndrome, sweats, painful muscles and bones etc. I was "kicking the habit" really).
Fast forward 2 months later and I got my prescription for Ritalin back for my ADHD and got a prescription for Diazepam to help me with stopping a 5 year Cannabis habit. I also got prescribed Tramadol and Codeine for my chronic back pain. Needless to say I got hooked on Diazepam even though I tried my best to avoid it, I would take breaks for a few days every week until I got withdrawal symptoms, then I knew that I was hooked without even knowing it. I get 30 mg of Diazepam daily and I have to take at least 20 mg every day so I won't get sick, so when it's weekend I give my Saturday and Sunday doses of Diazepam and Codeine to my mom so I won't slip up...
I still abuse the Ritalin on weekends because I don't drink much or do any other drugs besides psychedelics and prescription pain meds. But I have almost no withdrawals since I don't take them on Saturday & Sunday which seems to work, the cravings are still there though.
Basically I have six addictions now: Ritalin, Diazepam, Codeine, Tramadol, Nicotine and Caffeine. Currently I have 10x100 mg Tramadol ER, 10x100 mg Tramadol SR, 10x50 mg Tramadol IR, 18x10 mg Ritalin, 12x20 mg Codeine and 30x5 mg Diazepam in front of me. I got the Tramadol from a good friend and I bought 2 strips of Diazepam off the street, I might even have found a connection for Alprazolam and Clonazepam so I might get some in case I run out of Diazepam, stupid I know but that's all what is available on the streets, I can't even get simple MDMA or LSD, only loads of crack here which I won't touch. My life gets more complicated every day it seems...
This post is more TDS material but I want people to know how hard it can be to keep the addiction away, often you'll realize it only when it's too late.
My advice: pick up your meds on a daily basis, IMHO the best way to keep your tolerance at a normal level instead of feeling no effects from 100+ mg of Diazepam like I do...
Another long post from me, I had the need to tell my story so if you have read my entire post I thank you for that.

Good luck to all of you who have the same problem, Benzo addiction isn't fun...
