Forgive my confusion (it's been a long Monday), but you're now at .25mg, or at .5mg? Either way, you're rocking it! Way to go.
If you're at .25mg, if I were you, I'd try to go down a small amount and see how you feel, like to .2mg and if you do okay, stay there for 10-14 days and then drop again. If it hardly bothers you, you can always drop again and not have to stay at the new dose for a full two weeks. You seem to be handling the drops really well, which is so awesome.
If you're at .5mg, you could try to drop to .4mg, or even .45mg and see how you feel, etc. Or, if you want, try dropping to .25mg and if it gets too bad, you can go up to either .3mg or .4mg, etc., depending on how you feel.
I'm sure more experienced people such as Dotz and Cheeps will chime in too, as they are soooo knowledgable and give great advice.
Regardless, you're well on your way to freedom! Rock on sistah! You've got Sub-Satan by the balls, so squeeze 'em tight and don't give up! You're making excellent progress.
