second day, first reduction going from 50mg to 43.5mg zoloft after 7 years use.

Hi, I'm new here at the forum and also my decision for quitting is fairly recent. I was fortunate enough to find all this information for tapering safely, and I'm feeling a little overwhelmed at the extra long term period and the work that will be needed to be successful, but I'm also confident and motivated. This is my first reduction after being 7 years on 50mg of sertraline daily. This is my second day at 43.5mg and wasn't expecting to feel anything really, but I am noticing some strange headaches as I'm typing this. Feels like pressure in my temples followed by a lightness in my head, as if im floating. I've been off the medication for like one to two weeks before as I forgot my pills before a trip and the symptoms weren't this quick and clear. Is it normal? Also i am drinking my only cup of coffee of the day, should i quit coffee also?
