hmm, not sure, you have the opposite probelm to me in several ways; i always found that G stopped benzos working. I think the g was way too acidic in my stomach, and probably destroyed the Bzs before i could metabolise them, especially as i woudnt eat for 24 hours either after G, after having after bad puking experiences foloowing tring to eat with a 'G stomach.' The good news is that antacis like Rennie seem to work very well for neutralisng g in the stomach, if you wanna tke Bz instead of G that should be safe enough. (You may wanna wait for someone with experinece of a much heavier G habit and / or a greater understanding of GABBAgenics, as although i know taking g first renders Bz useless for me, i dont think im alone in that, but will taking BZs first do the same for G, i dunno.)
I always found that g kept me awake all night in a stimmed state otherwise, but im far more heavily dependant on benzos than G. in fact i not dependant on g, although it does now give me w/ds every time i take it now. Maybe i could not tocuh g for weeks, if i tried, but coulntdnt do that for Bzs. Hopefully my next paragraph will be more helpful for your situation..
It would be more helpful if i said that bacofeln and hash (sedative types) can be used to help ease any discomfort of G w/ds. My G habit has never been allowed to escalate that badly though, perhaps 3 sessions a week max, which did turn out to be too much and tipped the balance in that i now get w/ds every time i take g. bloody fool that i am, i should have learnt by now. I have learned abit but g was hard to resist sometimes, i ratioanlise it way in that i was using it to help me quit kratom. Yeah it did help with that, but i think i g problem could be a lot worse than kratom. Bacoflen and Preagabalin will help uou quit q, im pretty user that they are the same time of GABBA as GBL and so are used for replacemt therapies. your doc may prescribe, if not there are good online sources.
