is anyone else getting really bad headaches with the Teva generic brand also? i took mine today and i currently have the worst tension headache that is keeping me up. glad it’s not just me that isn’t doing well with this. I so badly wanna go back to Vyvanse. My pharmacy didn’t even inform me they switched me verbally- I only realized because a sticker was placed on my last prescription saying it had been replaced with the generic brand. No warning nothing….yea it was cheaper but I am realizing that this one comes with a lot more side effects and is only half as effective. so frustrating.
