I took 1 ketamine infusion 2 weeks ago for severe depression and now my brain fog is worse and I have disassociation feelings where I feel like I am in in a dream state. I really regret taking it. They gave me 1 mg/kg for a total of 60 over 1 hr. I heard .5 was a better doseage. Does anyone know of any medications I can take to deal with these symptoms? I am worried I did long term damage to my brain. My brain fog is the worst in the morning and it gets a little better by midday but it is always there. I also take Seroquel at night. Is it a combination of the Seroquel and Ketamine?. I am desperate to feel better.
