Can coffee make you sleepy if you're on klonopin and lexapro for anxiety?

I noticed after I stopped drinking coffee in Aug 2015 when I I was in the very early stages of pregnancy with my son, drinking coffee one morning on my way to work which always made me feel so pumped up, made my stomach feel flip floppy on the inside. I was iny early stages of pregnancy, so I put the coffee down and didn't drink or again until a yr later. Anyway, I was put on klonopin and lexapro after having my son in '16  for postpartum and still on the medications trying to start weaning off in March. I just came to the conclusion that coffee makes me sleepy now bc of my medications that already make me sleepy. I drink coffee for the taste basically now since it doesn't keep me alert anymore. My doc said "I don't know, but maybe. Why don't you stop drinking coffee for a while to see if you feel anymore alert until you start weaning off klonopin". Just wondering if anyone else has experienced extreme sleepiness after drinking coffee while on anti anxiety meds. Pls, no rude answers. Much positivity in the New Year!
