It depends on so many variables, probably no more than 3 months. If you really have some degree of autism or asperger, I suggest you reduce the maximum cognitive effort you can, so you can adapt faster. For example, remove other objects from the desk, put the chair against a wall (so you don't feel as someone is watching you).
You don't just adapt to, but also, in this case, nurture the experience around you. So, besides removing things you don't need, try to maintain the same things from before the change and then gradually change (again), until you adapt to it. It works similarly as "cold turkey" vs "gradual removal" on drugs.
You can also use behaviorism: every time something bothers you, and you can't change it, give some punitive measure to yourself. Read more on behaviorism and create your own protocol.
You can also use hormesis and spaced repetition: every time you feel unconfortable, give it a break, go drink some green tea, look at the trees, then you go back.
