Night Terrors

So I'm pretty sure L is experiencing night terrors. Every so often in the past, he'd wake from a sound sleep and cry and be upset and when we'd go in there, he often would not be able to tell us what was wrong. It usually wouldn't take too much effort to get him back to sleep and we'd be on our way but ever since the surgery, he's waking almost hourly screaming/crying/sobbing/inconsolable every night. I don't have to tell you how exhausting this is for both of us. My patience is wearing thin even though I know it isn't his fault but when I have to be up at 5am and I've been up every 2 hours with him trying to stop his screaming for fear that he'll wake O up is just exhausting for all of us. The last couple of nights, he's just come into bed with me when he wakes and sleepwalks/cries through the house. I just don't know what to do. I google this issue and there are some drugs out there but shit, I can't drug my kid every night and there doesn't seem to be much else one can do about this issue. I have no idea how long "waiting it out" will take and did I mention how effing tired I am? It's like having an infant again...seriously. I'm too old for this shit. I look like hell, I feel like hell, I'm uber bitchy and life certainly doesn't slow down for you when you're going through a rough spell like this.

If anyone has experience with this, please email me. I'm open to suggestions.
