Help with a Milk Protein Alergy baby

My daughter, Matilda, who is now 9 months old was diagnosed with MPA (Milk Protein Allergy) at the age of 3 months, and after numerous formula changes was finally happy with Nutramigen AA, which she has been on for some 5-6 months to date.
I think that her behavioural issues stem from the MPA, but if anyone could comment or give their experiences it may help...
Matilda used to be a good feeder before we chopped and changed formulas (under the recommendation of our health visitors, GP and pediatrician), although the feed didn't agree with her and she would cry for the majority of the time she was awake. With the Nutramigen AA the crying has stopped surrounding feeding, but she seems to have inherited some other issues... like not wanting to sleep during the day time and if she does it's for a really short period of time like 20 minutes, plus she wakes throughout the night, for no apparent reason, you can pick her up and rock her back to sleep, but 4 or 5 times a night is leading to sleep deprivation; if anything shouldn't please her 100% she will cry as if the world is ending almost like this is the only way she knows how to communcate. We have tried some controlled crying, but it leads to her getting hysterical, resulting in being physically sick. She is difficult at the best of times, doesn't appear to want cuddles, certainly isn't happy just sitting on someones lap, or lying down in bed with us.
Weaning is mighty difficult too, as she is entirely dependent upon her formula for calcium, which means that she isn't really interested in solids, and we are having difficulty moving her to the next stage (2). She has also recently decided that she no longer wants anything savoury, and will only accept apple or pear purees, and then in very small quantities.
I could go on! Has anyone experienced anything like this? Please help, we are finding parenting difficult with minimal enjoyment!

What about regular nutramigen? my son was on that til 12 months. and not i have him on gentlease toddler formula and whole milk and hes doing great. My son really didnt go for solids until he turned a year and now at 14 months old..hes still a picky eater.

we've done the regular nutramigen, but she threw it up everytime she drank it, but she mostly refused it due to the taste and smell. Funily AA tastes and smells not quite as bad, and she appears to be happy with that. I think I'm more concerned about her behavioural issues...
