I'm Having Laser Procedure 6/21 In My Bladder To Remove

I'm having laser procedure 6/21 in my bladder to remove a growth that doesn't allow me to empty bladder all at once. The instructions say to stop Vita E & fish oil 7-10 days before. Would that include Flax oil capsule, & what about calcium/magnesium multi vitamin & mineral tablets combination packet (Trader Joes) that I've taken since 1985? Also what about a tablespoon of coconut oil I take every day? Thank you for your experience & time. -Rick, age 66, 245 lbs. 5'9".
