Hello,

I have had both tests, fasting and other, after the first one I was fine, the second fasting test, I had a bad night before which might have contributed but I was sleepy, the staff were very attentive also and set me up in a spare room for a nap in between tests. which was great as the time flew by then.

I didnt have anyone with me, but went and had something to eat straight away, you might want to take some food with you, before you starting driving incase you feel weak from the fasting.

goodluck
