Hi Sunsoda-
If you don't have a tolerance, gabapentin helps mask withdrawal symptoms very well. It is a mood stabilizer. It helps with anxiety, the body temp issues, restlessness, sleep - basically all the symptoms.
Lyrica (Pregablin) does the same thing. They're pretty similar, with Lyrica being stronger.
I take both. Something I found, is even though Lyrica is the more potent of the two, I find Neurontin (gabapentin) more predictable and dependable.
There have been a few times I've taken Lyrica, and I didn't feel it, and it didn't help with w/d. It's important to note, that's rare, but it's still happened.
With no tolerance, and never using it before, or using it rarely, Lyrica would almost definitely work to alleviate withdrawal.
Neurontin, Lyrica, Buprenorphine (Subs), methadone - are pretty much the gold standard for withdrawal. Hope that helped.
