you dont have adrenal fatigue especially since you dropped stimulants.
The only way a non stim user could have adrenal fatigue was if you were at war in trenches and fearing for your life every second of the day. Your in college so stop stressing out, you have your whole career to do that.
Reset-AD will not do much for you. You most likely need a sleep aid so you can recovery better at night. Try diphenhydramine or better yet to get a good nights sleep and you will be able to take what is dished out to you during your day with more ease.
