Well I think that I might have to do something, I checked the SG today and it had gone down more but over a four day period it had only dropped .008. Four days ago it was at 1.138 and today it is at 1.130, That is a total SG drop of .030 so it is getting there but I will give it another few days and as long as it is dropping I will leave it alone. But if it stops I will probably split it in half between two 1 gallon jugs and refill with water. I might also add a fruit juice in one of the gallons to top it off.
So thats the update for now.
Ok, so "experiment, experiment, experiment"............
Now before you do anything rash and end up with double the quantity of overly dry, weak, "gnats piss".........
I'd start with two ideas......
Now if your hydrometer test jar is something like 100 mls, then take 50 mls of the batch and 50 mls of water - then see what the gravity is.....
alternatively, you could easily take 50 mls of the batch and then try 50 mls of a decent red or white grape juice (don't know which brands to suggest as I'm in the UK and you're in the US???). As long as the grape juice doesn't have any preservatives other than ascorbic acid (vitamin C) in it. Then mix and test in the same way.
You'd be better placed with grape juice than water as it wouldn't lose any "body".....
If the grape juice/must mix gives you a gravity in an acceptable range then that'd be excellent as you'd just end up with double the amount, but it's a pyment instead of a straight mead....
Oh, and if it gave you figures in the correct range i.e. something like 1.100, then I'd also chill the hell out of it first to reduce yeast activity to zero and then I'd take a little bit of must out to make a yeast starter, but using something like K1V-1116 yeast as it has that "killer" element to become the dominant yeast and also gives plenty of esters......
If you wanted, once the batch is split and up and running again, you could always feed it a bit more honey (say 1/2 lb at a time) to increase the alcohol and get a little more of the characteristics of the honey that you've used......
It's entirely up to you.....

p.s. Oh and I suspect it might need a good amount of ageing, like a year plus (got a couple of 3 year veterans under the stairs here.......)
