18 days since last prozac fise

Is it normal to have ZERO appetite & wake with pounding heartbeat & shaky?  Appetite will come back in dvening & I eat as much as I can. Feel almost normal again in the evenings but then afraid to go to bed knowing that it’s a cycle that will continue again in the morning.  Was only on 20 mg  (for about 13 years though). then weaned myself off within a month or so then went to dr who gave  me 10 mg to wean more.   Off completely now a little over 2 weeks.  Anyone have the same experience & how long will this last before I’m back to my normal self?  This is awful.  I need to hear something good here.   I do not want to go back on if I don’t have to.   

Also wanted to mention that doc gave me Xanax to help me thru these horrible side effects.  Primary care doc-haven’t been able to get into a psychiatrist in my area.  None are taking new patients.   sad
