Hi, @mamabear3 - that is a tricky situation to have your doctor leave the practice and then have a doctor you've not met take you off of a medication that was previously successful — the amphetamine and dextroamphetamine (Adderall) — in addressing your situation.

Here is some Mayo Clinic information on idiopathic hypersomnia that may be useful https://www.mayoclinic.org/diseases-conditions/hypersomnia/symptoms-causes/syc-20362332.

I'd like to introduce you to some Connect members who have mentioned hypersomnia and may have some thoughts for you on their experiences with it and what has worked for them other than amphetamine and dextroamphetamine (Adderall), like @notaround @manda304 @comtesse @sutter14 @bren1985. @tomgrinley @jimhd also may have some thoughts for you.

Is getting a second opinion from another sleep specialist an option for you?
