I got a 158 on the November LSAT, I have one more chance to write in January for 2020 admissions, should I write again??

(Applied to Ryerson, osgoode, queens, western, Ottawa and Windsor)

cGPA: 3.25, last two years: 3.8, two LSATS: 151, 158

For anyone who has written an afternoon lsat (12:30pm), do you have any tips to fight the afternoon sluggishness and stay alert?
