Last week (monday thru friday) i had an infusion of ketamine 500mg, magnesium 100mg and ldocaine 100mg daily for crps. Ihave have ketamine and lidaocaine infusions before. But this was the highest dose of ketamine i ever received. Today, first day post tx, i feel like my heart is racing, although my pulse is 70, i am anxious and when my eyes are closed they are fluttering making it impossible to sleep despite being exhausted. I did not experience any of this with prior infusions. How long do u think it will take for these side effects to go away
