Melatonin is fine. It has very few drug interactions.

I'm prescribed it and a polydrug user.

Hmm, checking again now, I do see user reports of withdrawal symptoms. I don't know about super addictive, but there does appear to be an addiction/physical dependence potential and it could be particularly strong for certain individuals. With that said, in literature it is considered to have a comparatively low risk, and the primary alternative is benzos which are notoriously problematic.

One nice thing about gabapentin is that your body can only process so much of it, and you will develop a tolerance at high doses. So there isn't much reward for chasing the high (if you're one of people that gets a high from it) with higher and higher dosages. After a certain point, you basically have to quit it for awhile if you want it to have an effect again. This limits the abuse potential.

Pregabalin (a modified form of gabapentin) is an entirely different story. It is reported to be addictive, with more OD potential, and worse withdrawal symptoms. The body does not limit its metabolism. It's by no means the most addictive drug, but it is known to be much more troublesome than gabapentin.

I don't know how much gabapentin you are taking, your medical history, your age, your body weight, etc. I'm also not a doctor. However 0.3mg of melatonin is a very light dose and melatonin has a good safety profile. If you're at a few 100s of mg of gabapentin and don't experience any respiratory depression from it or 0.3mg of melatonin, then I believe they should be safe together. Refrain from driving if you feel drowsy or otherwise altered. Generally it's things like benzos, z-drugs, heavy alcohol consumption, opiates, and prescription sedatives that you need to be more careful about mixing with.

If you can, it's a good idea to get comfortable asking your doctor and pharmacist these questions, as they will be the best-equipped to answer them. Of course, doing some research of your own and asking around for others' experiences can also be good for additional context.

Tolerance to the sedation developed pretty quickly for me. A lower dose can help too. I take 300 * 3/day

Synthetic opioids like tramadol work the best in terms of pain relief for me, but the side effects are pretty huge, so I only use them during really bad pain episodes. For more minor common pain where the neuropathic component isn't that bad, I take a NSAID called celecoxib.

Hey I'm sure it'll be fine, just remember, no one knows you're a dog on the internet.

In which case I recommend this tent because that's what we've been vibing with lately

something went wrong and I looked up a bear on the drug website

Yeah that sounds perfectly reasonable. Like I said, as long as you're below 1000mg a day you'll be fine. Gabapentinoids are extremely similar to alcohol in how they actually act in your brain, so at low doses they're perfectly manageable dependency wise. You'll probably notice your tolerance increases fairly quickly with the medicine, however the medical effects of it don't start lessening for quite a while so you'll be good there. If you're getting it for anxiety, they should keep you at a fairly low dose, 600mg-900mg a day should be the most you ever get. You'll find a sweet spot on them eventually and probably just stay at that dose because Gabapentin is a very different drug depending on the dose you take. It's very interesting imo.

I'm probably one of the people you heard saying Gabapentinoid withdrawal is terrible, but I was dosing myself on them so my tolerance climbed to the equivalent of about 4000-5000mg a day. At those doses, it truly is the worst withdrawal, but the first time I quit it my tolerance was only around 1000mg a day and it was pretty manageable. A little bit of insomnia and physical anxiety but nothing you can't just breathe through.
