Good luck with your taper! It sounds like it will be tough, but do-able. I've been lucky, that every time I have tapered off my meds, we have gone slow enough that I've never had any withdrawl symptoms (but then again, I haven't gotten any pain relief from these things either). It usually takes me several weeks to get off of a substantial dose of meds. I hope it is all smooth sailing for you, so to speak.
I did see the pictures of your models & they are beautiful! It really amazes me that the replicas look so real AND that they function! It sounds like a fun hobby. Unfortunately, I don't have much of any hobbies at the moment. Sadly, I can't even read for fun anymore.
I miss that terribly. Sometimes I listen to books on tape, but unfortunately, most of the books that I read are not on tape!
