Well the first day with the contacts I was able to wear them for about 3 hours and then I had a headache so i took them out. That was on Friday. Saturday I wore them for about 8 hours and everything seemed fine. Today I was able to wear them for about 4 hours and they became unbearable so I took them out. I wonder if I will be able to sleep with them cone Thursday? At thispoint it does notlook promising.
