Stimulants Muscle fasciculations after heavy extacy/ketamine use Day.

[Southamerica123]

i developed some kind of twitching after getting a high dose of extacy and probably ketamine in an 8 hour period + some kind of desrealization. Anxiety has made It worse during time. I made an EMG, Mri and bloodtest and everything is clean. Is this due to drugs or can be just because of the panic attack i had(probably ptsd) ? Still twitching persistently in calves and have other nervous system symptoms(tingling, pre cramps) after 10 months, been sobre since the incident. Before the incident i used Hard drugs only 3 times per year, and smoked weed twice per week
