Zoloft and appointment

Ive recently started taking zoloft for anxiety..just started on the 50 mg today after 4 days of 25 mg. The first two days were awful for me...intense headaches, feeling sick, nausea, tired, constant yawning, jaw ache from clenching and grinding my teeth. This is my 5th day and i am restless, i cant focus on study and keep putting it off. I am so tired i feel i could sleep through the entire week. my vision is slightly blurry...but not so bad i cant see the computer screen, however my typing is really bad...that may be due to the restlessness and agitation.
I have an appointment with the doctor tomorrow, even if it's only been 5 days im not too sure why zoloft was prescribed for me when its more for depression and social anxiety. Today in the car i felt really panicky, and i thought i could just fall asleep at the wheel or have a heart attack because my heart beat has felt even faster than before. If these side effects go away in a few weeks and i can be reassured i will start to feel better and happier and less anxious then i will continue them. However my university assignments are going to be really poor.

My boyfriend took Zoloft about 2 years ago for a two year period. He has 0 sex drive and it is effecting our relationship. I am in love with him; but, we need help. He doesn't have insurance so he doesn't want to go to the doctor. Is there something over the counter for libedo?

ive been on sertraline for about 3 years. i feel dissasociated alot of the time and it pisses me off, i dont know weather its becouse of the sertraline 'cos i cant remeber what it was like before i started taking it. im also really lazy and find it difficult to concentrate in lessons, but agian it might just be me. Im hating the dissasociatin though, especially now that my depression has been pretty much gone for a year. my psychologist is always buisy so i cant get an appointment to get off it. When i do get an appointment, it gets cancelled cos the dappy whench is always ill or something. grrrr, its annoying.
