hey just an update ,,,
i think iv figured out what the problem was i have stripped the viv and inspected everything and i have found that the inadequate setup the fool in my local shop has supplied me has a 60w max bulb fitting in it and it has been slowly starting to melt and breakdown ..(what an idiot and will be getting a large piece of my mind monday morning

).. the bulb i am using is a 75w reflector bulb , i think the fumes off the fitting ha been affecting her as i have now redone the viv and replaced the fitting with a 100w and she has started to pick up still not 100% but its a huge step in the right direction and i can now concentrate on getting her back and eating , i will keep you posted on her progress and its yet another little problem that may be of some use to others in the future with similar symptoms...
