6 days on lexapro. Horrible withdraws.

Doctor started me on 10mg 6 days ago and Ive already had to stop. Heart palpatations, panic attacks, profuse sweating, the whole thing. And that was at four days. Doctor told me that after six days, I can just cut off the dose. Has that been anyone elses experience?

Because let me tell you what. I deff am dealing with withdraws. The very day after i stopped. 3 days of no sleep, floaty head feeling, brainzaps, headaches. The works. Its been 7 days since I stopped and its slowly getting better but not by much.
