feather plucker - Lupron side effects?

I have a feather plucker on my hands, and need help.

I'm pretty sure I wrote about this at the start of all of this, but I am getting towards my wits end wanting to solve this problem because I hate seeing her like this, she's like my child. So I am reaching out again for help in the hopes I am overlooking something.

Around Christmas 06 she began constantly laying eggs. We tried everything, more calcium, reducing light, extending light, moving her cage around. Nothing stopped it. After a possible egg-bound scare I made the decision to start her on lupron. She has attempted to lay 2 eggs since, both that were soft shelled but were dismissed by the vet as a lack of calcium and possible side effect and I was ordered to make sure she has a good and daily source of calcium.

Since around September-October 2007 I'd say she began feather plucking. Earlier this year I took her to get evaluated, her yearly physical and was tested for giardia. My tiel will be 5 years old this July. She had a clean bill of health, did not have giardia, and I was actually told she was a little overweight, coming in at about 106grams. Since November, her weight has been fluctuating between 91-105 grams where she is currently back up to.

Nothing drastic changed from the time she was plucking. My job stayed the same, my time at home was the same, we haven't introduced new pets, a new home or anything really new. The only difference was that I cut her wings (after a long time of having free flight) but those have since grown out and the plucking continues. She started only doing it under her wings - She has always been a bit of an overpreener but she began pulling at feathers (and screaming at the top of her lungs) as she ripped it out. It first only was the white feathers beneath, but in recent investigation she has stripped out the feathers all the way down to her thighs - but she is doing it ALL beneath other feathers, as if to hide the evidence of this. Unless I nudge feathers out of the way, the plucking is completely hidden. But now it seems she might have started pulling on them on her chest, there's a little spot that is starting to catch my attention and this is stressing me out. She eats well, pellets, fresh vegtables/bread/kale and a measured amount of seed daily and has two calcium perches in her cage, she gets 12-13 hours of sleep nightly in dark room/cage and gets daily sunlight and warmth. I try to give her baths 2-3 times a week. Her cage has toys and shredders, papers and kleenex distributed for her to shred but often it gets ignored.

I decided to try the aloe vera bath spray sold at petsmart and while it soaks into her feathers well, now it seems that she isn't preening all the feathers when it's done, and she just looks very disheveled and I am worried the spray is drying her out worse and making any itch worse, not better. I plan to give her a regular water bath when I get home so that she cleans herself up a little and wipe away any discomfort in the case that she hates how this spray tastes and that's why she isn't fixing herself.

I contacted the doctors again who said that its possible the sexual frustration as a side effect from the lupron may be causing this, but they've told me she needs to stay on the lupron due to the egg laying and that not getting these hormone shots might be what is triggering this. So it seems that now I've started, I CAN'T stop them for her sake (even though I was told in the beginning that after a few shots she shouldn't need them other than every few months.)

So I guess that's really it. Does anyone else use lupron or can share in a similar experience? I am sorry this message is all over the place, I just wanted to try to answer any questions I might get upfront. Thank you for any assistance anyone can offer.
