So, an update. While the pain is still present, I feel lighter. I think the edema in my legs is steadily going down (at least, they're not pitting so easily)
I'm very tired, or keep feeling like I can always go back to sleep, but the sleep feels restful. I mean, I've got over 3 years of sleep debt, so I'm not going to be surprised if restful sleep is demanded from my body for a while
I forgot to take the hydroxyzine, so I didn't have huge chunks of uninterrupted sleep, but was able to keep sleeping despite those interruptions for about 12 hours?
