Talk to Psychiatry on Medicine Timing

Hi I am taking brintillex for anxiety/depression since two weeks. My psychiatrist suggested I should take it at sehri time in Ramadan but I couldn’t wake up for sehri and missed my dose of brintillex. Now I am thinking of taking it regularly at iftar time so that there are no chances of missing it in case I don’t wake up for sehri. I have two concerns though; 1) will it interfere with my night sleep if I take it at iftar time? 2) will it work the next day if I take it at iftar a night before? I’ve heard that it works for only 10-12 hours after taking it that’s why it’s suggested to take it in the morning.

Please help. Already have a lot of anxiety don’t want this to be a contributor aswell.
