" I feel like I have too many things running through my body but my doctor says otherwise. "
You are correct and your doctor is wrong.
Did your doc warn you that
Chantix may cause you to become suicidal ? The "crazy dreams" and "poor self esteem" are bad reactions to Chantix.
"Lethargy from the
Xanax" could be a symptom of overdosing on these drugs.
Whenever you get sick, you need to sleep. That's how the body repairs itself. I believe that "feeling tired" or a "lack or energy" are symptoms of your body trying to deal with you ingesting too many chemicals .
