2 weeks doesn't seem like that long to persist with a major change like swapping from sitting all day to standing. Would be interesting to hear from someone who persisted with it for longer to see if they were able to adjust fully. I have a desk that is adjustable from sitting to standing and enjoy it as it lets me work longer without my back annoying me.
In regards to the 135 degree suggestion, I've found this doesn't work well for me, my lower back hurts, and also it encourages me to stick my chin forward which puts pressure on your neck. Could be a result of body shape or specifics of my setup though.
