Help! Need dosage reduction advice!

Hi again! Several of you have been a great help to me but I'm in a scary situation. I have been on Paxil for going on 4 weeks now and had been taking 10mg first week then my psychiatrist upper it to 20 mg for two more weeks and then I started feeling sick and so spaced out I couldn't function and then he put me back down to 10 mg which is where I have been for the past 6 days. Thing is I got really sick to my stomach after coming off the 20 and then started feeling better Tuesday and Wednesday but then today after I took it I had a constant buzzing feeling nervous feeling the entire day plus spaced out. It really scared me! I don't want to take this paxil anymore and I wonder if dropping down to 5 mg in the morning will cause me more problems or do I need to stay on the 10 and it will get better? I'm really scared of feeling this way again. I pretty much isolate myself when that happened and didn't want to be out of the bedroom! My Dr. Is out of the country so can't really get any advice. If anyone has experience with this I appreciate your advice.
