Adult ADHD Non-stimulant Medications

I was diagnosed with ADHD, present from childhood, 35 years ago. I took stimulant meds for a few months, but stopped and haven't started them again. Has anyone here taken any of the alpha agonist non-stimulant medications ( clonidine and guanfacine) ? Can you relate your experience with them, including effectiveness for emotional regulation and any side effects?
