I don't have a regular doc. I have no insurance so I don't being able to keep my neuro was a blessing. He only charges 75.00 a visit. Maybe I'll ask him for the blood test. Do you think it would really matter? I was technically on the drug for only a month. I was on for 2 weeks had a bad reaction then he took me off for 3 weeks then back on for 2 weeks and the same reactions even with preventative meds.
