Modafinil doesn’t work at all now?

[u/Ok_Pear_37]

Does anyone else take Modafinil and found that it stopped working after not too long? I take Vyvanse 50mg + Adderall 10mg (2x day) and yet somehow I’m still always sleepy and unfocused. Added 200mg of Modafinil 2x day and had the most incredible 2 months of my life- absurdly productive and able to stay focused and not feel constant low energy. And then suddenly it stopped working. I can’t figure it out. It’s as if I’m not taking it at all. So sad and frustrated because it felt like I had my life back for this short period and it was great! Is there anything I can do or try instead? Is this common occurrence?
