Is Motivation Issues A Common Thing WIth ADHD?

I can't tell if I have problems staying motivated or if I just can't focus on my goals, but I can't seem to keep a routine very well when it comes to things like working out and keeping up with seemingly basic house chores. I was diagnosed with ADHD as a kid, but once I lost access to medication in high school it feels like it's been a slow downward spiral of losing the ability to study, plan for and carry out long term projects/goals.
