I feel for you. It might be night terrors, have you looked into that yet? The thing that gave me the idea is that you need a light to wake him up, and he doesn't just wake up from it when he is moved. We had a lot of luck with keeping the room cold (like about 60) and keeping a noise maker on, we use a fan.
We dealt with acid reflux and night terrors with our little one. If he is under 25 pounds, then I would get a Graco Sweetpeace Soother for him. It is a swing that has the correct angle like the wedge, but since it swings, it will help get the gas out as well.
You can also use a liquid anti-gas/antacid like Maalox, or Mylanta, I get confused which one is which, but it is white and chalky. Use 1ml at a time and just squirt it in his mouth. I have used up to 5 ml at a time and you can give it every hour or two.
Finally, have you tried a dairy free and soy free diet? My kiddos were so bad, that I could eat either one while I was pregnant, and the trace amounts in food in the hospital were too much, so I had to switch for Alimentum for both of my kids. Sometimes, breast milk is just too much for them from what you eat. I didn't realize it was what I was eating that made them so sick for a long time because it was such a small amount in things.
I hope this helps. I also agree that he needs to sleep longer, he should have 2 long naps a day at least! but a tired baby will sleep less than he should because he is overtired. We also dealt with this, and when we finally got him to sleep more he felt better and slept better at night.
Good luck, I wish I could help hold and rock him so that you could have a break. There is another place on Facebook called the Fussy Baby Site, and I would look there. I didn't find it until my 2nd one, but since he was worse than the first, it was still helpful. Those moms and dads have so been there and done that!
Oh, one more thing, I if you can, feed less more often. This will help with the acid reflux. We had to feed 1-2 oz every 1.5 hours instead of 4 every 3 or more. I think at 8 months we were up to 4 oz every 1.5 hours because our guy is a moose, so I am not sure what you guy needs. A bottle does help control this. You can't let them eat til satisfied, because by that time he will have eaten too much to make his tummy feel better, and then it hurts again. :(
