^is it easy to get opiates prescribed to you in Belgium? Do the doctors give it out easily? Do the pharmacies cross check against all other pharmacies to make sure you can only fill one script?
For me personally, yes. The first GP I went to after my doctor retired, prescribed me 2x80mg OC / day (with a third one/day if needed - so let's say 75 OC80's per month, then also 12mg bromazepam/day). He started giving me these prescriptions when I showed him my file that I got from my previous doctor, (the one who retired after new years this year; he prescribed me even more opioids/iates, about the same amount of oxy but also a bunch of ms contin, as well as an additional hypnotic benzo for sleep).
But it's actually really not easy at all to get these medications prescribed here. I get them easily because of my file, my chronic pain issues + the doctor knows I will move on to IV heroin if he doesn't give me oxycodone (which he thinks I take orally). So I guess I'm 'lucky' in this regard, I don't see anyone else going to the same GP I go to now and walk out with 2 scripts for 30x80mg OC & 60x12mg bromazepam.
There is no way you can fill the same script twice. They scan the barcode on the script, and once you fill the script, that barcode becomes useless. If you somehow manage to hold on to it after filling the script (which never happens either really, they keep the scripts you fill obviously), and go to another pharmacy they will notice it has already been filled as soon as they scan the barcode on the script.
I did get 2 scripts of oxy today, and I know of two pharmacies nearby who stock oxy 80mg (not many stock oxy stronger than 20mg, since 80's are prescribed so rarely). So I went to both pharmacies and filled one of the scripts per pharmacy so I could get both my boxes of oxycontin at once and did not have to wait for them to order my second box. I'm pretty sure that when I go to 2 pharmacies back to back, the second one can see that I
just filled an Rx for oxy 80mg in another pharmacy only about 10 minutes prior to showing up there. But they can also tell that the script I give to the pharmacist at the 2nd pharmacy isn't the same one as the one I just filled at the first pharmacy, so that's not an issue whatsoever and I can fill both scripts at the same time. If they would stock 2 boxes of OC80's at the first pharmacy, I would have just filled them both there. So long as I have the scripts and they don't have a 'Can not fill before X/X/2017' printed at the bottom (X/X/2017 meaning any date in the future), I can fill as many scripts as I want to all in the same day, hell, in the same hour. :D
OT: I'm on oxy but I'm borderline sober again, it's been a few hours since I've dosed anything. So I'm about to shoot up an oxy, and I'm going to pop 2mg xanax as well. I would take one of the pentobarbitals I have, but I'm pretty sure I would just fall asleep and it would go to waste since I didn't sleep last night (was up all night on ethylphenidate). Going to watch some TV, hopefully nod a little and then go to sleep at a 'reasonable' hour. I also plan to sleep in tomorrow so I'm well rested tomorrow. I'm definitely taking a phenobarbital tomorrow, don't want to waste it by being too tired and falling asleep, hah. Will probably mix it with methadone since they're both long acting - meaning I'll have to dose only once to be high as fuck all day!
Good night sweethearts!

Time to enjoy that oxy & xanax now!
