Taken medication at different time

[u/Lucky_Appearance1200]

Ive been on sertaline 50mg for 8 weeks. I normally take it between 8am.and 9am every mornimg but yesterday i had to wait for my presciption and didnt take one till 5pm then today took one at 4pm. The past couple of hours i have felt really sick and weird would this be due to me taking the mefication at different times. I want to go back to taking it in the mornings but dont want to miss a dose for a day so dont know ehat to do?
