Effexor XR to Zoloft

Hi everyone.  I just had a few questions I would like to put out there if I may.  OK, so I had been on 225mgs of Effexor XR since 12/06.  About a month ago I asked to switch to Zoloft for many reasons, mostly because it seemed ineffective.  I dropped to 150mgs for about 2 weeks then stopped the Effexor XR and started Zoloft 150mgs.  I really haven't had any withdrawl (withdrawal) symptoms except that I am ALWAYS freezing cold, yet I continue to sweat badly from under my arms, especially in the mornings.  Does this sound normal???  Shouldn't I have had some other withdrawls???  I guess I am afraid of something coming on all at once.  It has been a few days over 2 weeks since I took Effexor XR.  
Thank You.
