I am taking Vyvanse and Prozac, and I'm having trouble getting myself to eat. I am still in a healthy weight range, so I'm not worried about that. But I've been weak, fatigued, and dizzy at times because I'm not eating enough. Are there any protein shakes I should try, or something like that, so I can be getting the nutrients I need? I hate most protein shakes because I can't stand the texture, and they're usually gross. But I have to do something.
