hello OP, with your post you have pretty much answered why it is so important not to purchase a huge amount at once and that's especially from a vendor that you are not sure about and getting pills that you are not sure about. from our discussion that we had a while back I understood that you are on about a 90 mg per day, is that true? if that's so then I can assume that you are taking a few pills once in a few hours per day, true? well, having that said, if I would be you then I would firstly try to experiment and that's why I would take only one pill and I would try to notice the effects that I have had from that pill. I honestly think that you should do it before you are taking several of them because in this way you would find out how exact potent is that pill.
also, just out of curiosity and interest, how are you actually feeling when you are using so many of them? what kind of feelings? are they making you feeling sleepy? what about your physical aspect? are you looking/ acting fine? are people asking if you are feeling fine or there are no signs that you have taken those pills? also, do you combine them with codeine too? or when you did then did that zonk you?
I guess the reason why I am asking this is because I simply cannot imagine myself using 90 mg of diazepam and to be able to walk around like nothing happened, to talk fluently and normally, to do housework, errands like you are able to do it all. personally for me, the maximum that I am able to take is only 20 mg of them and then I am already feeling very sedate. can you imagine what would happen at 90 mg? that's surely not the right dosage for me.
also, just in case you have not tried xanax then I can tell you that all that they are doing it is to make you a little bit dopey and everything that you want it is to just sit down and to relax, to sit down. once, I could not be bothered to simply just get up and to make one phone call. that's how bad it was for me this sedation and this desire to just relax. it was really bad because my phone simply was in the other room so I had to get up, to get there, get my phone and to come back - no, it was too much for me. that's just to give you an example of how it is/ was for me. however, instead of that I just have sat down and I have watched some crappy TV shows out of being bored. a complete and total waste of a day off. I remember that I didn't even wanted to get up to eat something. but anyway, again, that's just me. I would say that you just need to be more concerned about them being spiked with something that is more deadly. I am having absolutely no idea at all what 9 xanax tablets would do to a person but to be honest I am too afraid to even think about it. I would be very afraid to take all of them myself. I just imagine what it would do to myself. anyway, I just can guess that you would just feel very and very zonked, extremely sedated. at least I'm talking about myself. plus, knowing how much it relaxes me then it wouldn't be a big surprise for me if I would wake up 2 or 3 days after taking 9 xanax pills and having the worst hangover ever.
anyway, the very best way that a person can tell (in my opinion) is when they are comparing a GP prescribed one with a bought from the streets one. well, I have went to a chemist and I have got them in order to check the barcode and then I have seen that those pills turned out to be some excellent counterfeits! I also should mention here that I did have had crecents, in facts, I have had teva, actavis, crecents, martin dow and almus from pharmacies and I honestly cannot tell the difference in strength wise. If that says about anything to you. I did have had pax/ bettas. roche (lol) aups/ bens and here, between them I can say that there was a difference (or at least a different that I could feel). anyway, I really hope very much that your mental health/ drug team and so on and so forth is going to sort you out with some pharma grade diazepam as soon as possible so you would feel fine.
but yeah, one last thing that I wanted to say here is that there is some xanax that can be cheaper than diazepam because of some different things. like for example the gador and upjohns bars are being expensive (quite expensive) while all of the other ones are as cheap as some chips (in some of the places literally giving the exchange rate and the fact that a fish and chips are now nearly a fiver). I wish you all the best and good luck, hope you're gonna be well and I also want to tell you good luck with your tapering plan.
