I'm going to try to give this some more time later, but it's worth noting that even those these drugs are chemically, very similar, they're often not fully interchangeable and Baclofen, in comparison to other well-known Gabapentinoids, is typically less-desired for its ability to mitigate withdrawal symptoms. Phenibut is typically more effective for this purpose, but that doesn't mean Baclofen won't work.
OP, it's not out of the question that you would receive the same benefit from Phenibut that you might from Baclofen. I would recommend trying it out. Are you going through all available channels to get the best price for your prescriptions? Unless you're on a higher than what is typically prescribed dosage, this medication should not be $300 /month.
This is me talking out loud at this point, but I've witnessed anecdotally that although Gabapentinoids are all chemically similar, in a given individual, one can be quite effective while another is ineffective. Then, there is another individual for whom Gabapentinoids act in a linear fashion and are all cross-tolerant, essentially.
What I'm saying is that, someone might just love Gabapentin (Neurontin), while say, Pregabalin (Lyrica) makes them totally dizzy and they hate it. It's an interesting phenomenon.
