You consume a fatty meal/snack. Then take 300mg. Wait an hour. Take 300mg more with soda. Wait an hour. Take 300mg with a fatty snack. Wait an hour. Take 300mg more with a fatty snack and soda. Repeat until you get hit with a ton of bricks.
I suggest sitting down and having a bed close by. Once it hits you you'll find walking to be very hard.
Going to add to this because I just happened to plan on taking gabapentin tonight. I started with 12 300mg capsules. I just counted and I have 5 left.
I started taking them with about an hour delay in between around 6 or 7 hours ago. I followed my stacking advice above and had a fatty snacks while taking them. Tonight I had a cheese burger and peanut butter crackers along with them. I ate something every other time I consumed a capsule.
Mixed it with my usual kratom intake (about 3-5 grams per dose tossed and wash). I've also had about 10mg of 7-HO and 5mg of pseudoindoxyl. The 7-HO and pseudo I take sublingual. But I typically don't hold them under the tongue too long and swallow it quickly. With the kratom already in my system both of those last much longer and I can actually obtain a nod. You don't have to mix opioids with Gabapentin or pregabalin but both do mix well. Benzos also mix well but I don't have any tonight. I've already taken xanax once this week and I don't like taking it often.
Anyway by the 7th or 8th capsule many hours later I'm starting to get positive effects from the Gabapentin. All pain is gone. I'm starting to feel wonky. My balance is starting to get bad. It won't be long now before I'm stuck the couch for the next 12-14 hours. This drug can actually provide amazing CEVs if you take it correctly and stack doses like I have. I expect I'll have a good time soon.
If you take them all at once you'll just end up pissing all of the drug out without it doing anything. You have to use the stacking method over many hours to get enough of it in your system to get positive effects beyond general pain relief. It's one of my favorite substances but you do have to plan your entire day/night around it. Right now I'm in the drunken social mood. If I was at a party I'd be yammer on to anyone that would listen to me. It makes you write walls of text like I'm doing now if you're taking it alone and near a computer. Another pill or three and I'll be so out of it that reading the screen will become impossible. It's at that point where it's really fun. You have to lay down and close your eyes. If you fight the urge to sleep you'll start to hallucinate and get waking dreams similar to morphine dreams.
The guy above is right it'll give you random spasms in the days that follow and you won't feel 100%. It is not a bad feeling. It's most like you're still kind of wonky but you feel good and there isn't any general pain. If you suffer from chronic pain like I do the days after are really great because you can't feel the usual aches and pains.
Tolerance also builds quickly. It isn't something you can do everyday or every week. To get positive effects you have to do it once or twice a month. It always requires having a supply of 10+ pills on hand. I started with 12 tonight and I'll have 1-3 left over tomorrow. Generally I will take those over the course of the next couple of days to help with the spasms mentioned above.
I do sometimes worry about what it's doing to my brain long term. But I've been taking it for 15+ years now without issue. It has caused me less grief that most of the other drugs I've taken and been addicted to. I've never felt like I was getting addicted to it. Probably because it doesn't work if you try to do it two days in a row.
I've used it socially in the past many times. It's always fine if you're sitting around playing video games or something like that. But the moment you try to stand up everyone will know you're on something. I've had to catch myself on coffee tables and end tables many times in the past. Always get caught that way. Which is why I prefer to do it at home.
I've also found it to be very effective for opioid and benzo withdrawals. It helps you get through acute withdrawals and masks some of the symptoms. I think it's much better than phenibut. I like phenibut but I've never gotten to the hit by a train of CEVs space with it. The one time I took a bunch of phenibut I had a really bad time. Could barely walk and was shaking like I was having a seizure. Gabapentin has never done me that way at least when I was awake.
I have taken Gabapentin in the past mixed with other drugs and woken up feeling like I had a seizure while passed out. But I can't be sure. Since I've gotten more careful about my drug intake that hasn't happened again. I'm not exactly sure what caused it but I suspect it had more to do with the daily intake of benzos than it did with the gabapentin.
Give stacking doses a try. You'll know when it starts to work. It's a really unique drug.
