... Only a cup of coffee. Is this considered as not having an empty stomach and I should wait 2 hours after a cup of coffee?

Also, I don't eat 3 meals a day and don't eat dinner at the same time each day. All of this is due to having a very ill husband and having to care for him prevents me from having a "schedule" for eating, etc.

I am having no side effects from taking this med, but I need to know if a cup of coffee or a soft drink comprises having something on my stomach. Thanks for help
