Hello. I have recently been prescribed zoloft and dextroamfetamine (vyvanse). My dose has just been raised to 150 zoloft and 50 vyvanse. I am feeling dizzy, I'm sweating like crazy lying down in a cold room, and I've thrown up a few times since I took the increased dosages earlier today. Occasionally it feels like my heart has butterfly wings too. Am I just having panic attacks? I heard the dex can increase anxiety...
