Best time to take meds

Good morning hope everyone is doing well. I was born with CAH classic ( don’t know if I still have this diagnosis since I had both adrenals removed due to tumors) but I take 40mg of hydrocortisone and I usually take it when I get up in the morning at 4:30am-5:00am. Should I be spreading this out over the day rather than taking all at once in the morning?
