I think people misunderstand the power of gabapentin considering that it isn't a controlled medication, even most of the psychiatrists that I've worked with sort of shrug when its mentioned and ask what dose I'd like to be on. Also due to the the nature of gabapentin not producing a very noticeable "high" even those of us who take it might think that to stop taking it will be a breeze, but its definitely a strong effective medication at least in my opinion. Due to gabapentin acting on GABA-B as opposed to GABA-A or GABA-Z, both somewhat more commonly seen in American society, it tends to be something our body is unfamiliar with and there aren't any great substitutes for it. Phenibut, Baclofen, and GHB all also work on GABA-B but i don't thin anyone who knows much about those three would advise their use to help come off gabapentin for relatively obvious reasons. I mean although I take my gabapentin as prescribed there have been times when I've run out of my prescription, saw doctor at a different date than usual and didn't bother to call him and have the gabapentin script called into the pharmacy, and wow do I become irritated and generally unsettled maybe even more paranoid than usual. I've been in one of those run out of gabapentin situations while heavily abusing opiates before and even taking an extra 80mg OP Oxycontin or 2 didn't make it so that I couldn't feel the gabapentin withdrawal, as a matter of fact I think it made me feel worse. Of the medications you said you had available to help with the withdrawal propranolol and clonidine caught my eye as the ones which may be the most helpful as lowering blood pressure has often helped either make me tired , sleep is a great way to deal with withdrawal in my opinion, or lower blood pressure relieves anxiety for me. The medication I've found most helpful in dealing with gabapentin withdrawal oddly enough has been Guanfacine (Tenex, Intuniv) which is prescribed to help treat the symptoms of ADHD, it also lowers blood pressure and taking 6 mg of intuniv would make me sleep like a baby for the whole night. Anyways that is some of my thoughts pertaining to the odd medication, gabapentin; take care and good luck
