Don't know what good advice I can give you , Heid other than my own personal experience with it.
Im very sensitive to meds and was prescribed Paxil as well. I was also prescribed Xanax while I tried to weather the beginning seide effects til it stabilized in my system. I can say that time period was pure hell and mroe times than not I didnt think id get through til it adjsuted.
I didnt get the headaches you speak of...but maybe the blurred vision is a form of the headaches you had?
I took it alot slower than most people...a quarter of a pill for a week...then a half...then 3/4 and finally after a month I was up tofull. And it was very hard to be honest.
BUT once I was there the benefits paid off. It helped immensely jsut had to deal with til I got leveled out unfortuantely.
The thing syou mentioned dont sound medically alarming though I MORE than understand how you feel. I thought for sure something wasnt right and it scared me alot. Its good that you ask someone "official" so they can either reassure to be patient or sugget a different med maybe.
Hoep you get it sorted out quickly, g/f...I knwo it can be scary when its suppsoed to be helping.
