First time use. Weird effect thus far.

So I've taken time to research everything. I've been sitting on 4 400mg gabapentin capsules for a month or two. Last night I figured I would try it. So I did, this morning.

I ate something, drank soda, took the first 400, ate a spoonful of peanut butter, waited 40 minutes and took the second dose. By this point, I felt a little bit of a buzz.

But then I had to take a 20 minute long shit and by the time it was over I was back to feeling sober. Took my third dose just a little bit ago. I'm now at a power level of over 1200mg.

It's been about 2 hours since I began and I'm still not feeling the buzz as much as I did before I took that shit, however. Should I take my last capsule?
