I also do not medicate. Never even tried it, largely because I felt spiteful about how my providers and teachers talked about it when I was a teenager, then I learned some coping skills as an adult. Here are some things that help me succeed:
-I sleep using a weighted blanket. I just started this and cannot stress enough how successful this has been. Normally I constantly feel the need to move when I lay down and have a hard time turning my brain off. This provides an overwhelming sense of well-being and calms that irritability that makes me want to be moving or notice strange sensations on my body. It also makes me not think stressful thoughts at night.
-I put my hand over my mouth when it’s not my turn to speak.
-I cross my feet and put them under my chair when I am in meetings to prevent bouncing my knee or other types of fidgeting that will distract my coworkers.
-I talk to myself to try to keep me on track.
-I give myself time to take walks.
-carbonated water only, no soda.
