What meds are safe to take with Hypothyroidism disease?

I am 18 and just got diagnosed with Hypothyroidism. I know it’s not a HUGE deal, but I am on Synthroid for it and on 40 mg of Adderall for ADD… but my adderall doesn’t work anymore since I’ve had hypothyroidism! I used to just take 20mg and I would work like crazy and I couldn’t go to sleep for days on it, but I tried taking 60mg and I was still tired, sluggish, and unfocused! Does anyone know why? Or if it is safe to even mix these drugs?! I am also on Zoloft for anxiety. Please help!
My doctor KNOWS all the meds I am on. Im not retarded. Im just asking if anyone else has had this happen with Adderall.
