It's bad. I was put on sleeping pills by my therapist. But I love to exercise in the morning!
Today was my first experience with this problem. I thought the pills' effect would have vanished by morning but no. Plus, I like to exercise on an empty stomach very early in the morning. So today was like my worst day of exercise ever.
I didn't realize it in the beginning but halfway through my workout I had this weird and unusual feeling then realized that I was still sleepy/drowsy. I had to stop.
Whatever the case I don't think eating would prevent me from feeling the effects of the drug.
What can I do? Changing to the evening is definitely a no-no because of my schedule.
