I always wait 10 hours between taking my meds and my test.

How are you feeling, I'd think that if you were toxic you might be feeling some of the co-ordination problems, slurred speech, vomiting, harsh tremors. But maybe not. I think I'd play it safe and not take anymore until I talked to my dr.

I had toxic levels once, it felt a lot like being drunk in body not mind.

I hope your test timing is all it was.
