Hello Tea…  I hope by now you found some info on this… I heard from Tana A. on a podcast that she has used Modafinil / Prov.. and I have also had 3 Rxs of it 200mg per pill experience with it.. Love it ..better than the standard RX for Add.. Adderall XL less side effects much more useful for me..  Adderall  made me tense and grouchy and I felt tense muscles around my face with it… and is not the best for all types of ADD.. Great at first but after a while this is what showed up for me.. ..Modafinil  sill available but can be pricy.. Of course one need to see an appropriate doc for the RX.. I am sure the coaches here can give you more guidance if you need.
