When I have shadows, they often tend to be the same 'ol right behind the eyeball routine, same as real CH hit, but mild in comparison.
With those there can be a fine and tricky line whether to consider them shadows or mild attacks though, right? For me, if they last more than 3-4 hours I feel I can legit label them as shadows.
Now Im getting a lil' worried, because what you're describing would be warning signs for a cycle wanting to rear up for me. Hopefully different for you, but I'd sure be trying to find a way to prioritize a bust. Granted that sounds tuff trying to sleep through RC with the whole Abby situation, but maybe we can take a vote here whether you hubby could be asked to hold down the Abby fort one night while you luxuriate in the spacious regular bed with some RC. I vote yes. Not sure who might despise that scenario more though, poor Abby or the poor hub.
