I know this topic is old, but it remains interesting.
I wear a small 0.8" (2cm) lift in my 2cm thick shoes almost everydays, and it gives me a lot more confidence. I think 2cm is a good compromise because there is not too much difference when it becomes necessary to take out your shoes. In addition, those lifts are extremely confortable.
The point of beeing LL for me is to free me from my height phobia and also from the risk of beeing caught with the lift, so if I achieve my 180-181cm goal, the point is to remove them most of the time. Especially in my family and with friends, because I will probably not tell them that I did the surgery. They are so much used to see me with my artificial height for years of about 178cm (and not my actual 174), that if i go to 180-181, my best bet in family will be to buy some 1cm flat shoes, to remove the lift, and walking most of the time bare foot and without searching the best posture. They might however notice something like 2 or 3 cm of increase, but i think I'll tell them that my back needed to be corrected with kinesitherapy, which could explain the 2/3cm difference.
The rest of the days I hope I will remove the lifts and choose shoes I like and not always thick and tall ones.
The only times I may put the 2cm lift in my shoes may be for very special nights (like at the opera), special date with a very tall girl or a trip to germanic/nordic countries, may be.
But the goal here is really to remove them at least 95% of the time, to feel almost "healed".
