I would suggest spending some time with some first. They can be very demanding. With your work schedule, you can make it work but you'll just have to be prepared to put in more. My Too takes up about 3-4 hours of my day, everyday. I am a full time student, and I also work. I make Rome work with my life because I want her to. My first bird I ever had was a U2, then I had some teils. Toos can be okay for first timers, as long as you understand them. That being said, I myself never wanted another Too (ever). I ended up with Rome by chance (I have the mentality for Toos so its fitting that I have one since so many cant handle them, but they require so much more out of you, thats why I didn't want another one - higher ups decided different :21

. My day with Rome goes like this, I spend my morning preparing everything for her (her food for the day, fill all of her foraging toys, a little cuddle time for her), this takes about an hour. Then she is put outside for the day. Around 4-5 she comes in and we spend time one on one (training, cuddling) and time just being around me until 7-8pm. On the days that I cant do this my Boyfriend steps in and tries to fill my shoes (emphasis on tries, remember your partner when considering whatever bird you choose). My schedule works because I have help with her and I have got her where she spends most of her day foraging so shes occupied. She is loose all day and only is caged at night when she is inside. When she first came to me she was way over spoiled, now I have gotten her to act like a bird in my absence, vs. just sitting there. You need to be careful because it is very easy to over spoil one. By this I mean the bird will scream when its not happy. You have to be able to ignore the scream (never own one if you live in an apartment or have roomates). It has taken Rome 3months (and still is a working progress on occasion) to realize that screaming doesn't get you what you want. This is 3mo. of SCREAMING from a M2, not fun. However when I commit myself to something I commit. If you bring one home it takes a long time for transition to find out if they are going to work or not. They are very very sensitive birds. Give the bird a full YEAR before considering whether its working or not. By the time a year is up your bird should be settled. This means no matter how difficult one may be, you HAVE to be committed to it for a year no matter how difficult it may be to live with. So if you go pick one up you need to make an oath to it and commit for a year regardless, when you have a Too it comes first and you second.
I would also suggest going and meeting a few to make sure that you are not allergic to them first as well. Some people are allergic to their dander, that their entire bodies are covered with.
With all that being said, I do love my M2. She has a wonderful personality and I wouldn't trade her for the world. I attached a pic of the area that she spends her day in so you get an idea of what I've done with her. Most Toos don't like to spend their days in cages. You just have to figure out your limitations, only you will truly know. Good luck with what ever you decide.
