Hello, Doctor Grief. I am currently under treatment for mild depression. Clinically speaking, my level of depression seems to affect me by what can best be described as impulse control problems, that often cause me to be moody. In the past, I have been prescribed Citalopram...which HAS seemed to make me much calmer. I am a Medical Assistant by profession, and so I have a broad knowledge of pharmacology. I know that Citalopram is a Selective Serotonin Reuptake Inhibitor, although I don t believe that my depression is due to low serotonin levels. I am currently taking Carbamazepine (Integratol), which is effective in treating seizures, but is also known to be a mood stabilizer. Although I am not really experiencing any adverse side effects from having taken it for about a month now, I had originally petitioned my doctor to consider prescribing the Citalopram, as well as consider switching me to it. He advised me to just give the Carbamazepine a try, although I had told him that I was having some difficulty sleeping. I have found that increased levels of serotonin help to induce sleep. Although I respect that your practice is not in Psychology, I am interested in your opinion as to whether increasing one s serotonin levels to help them relax to get more needed rest is medically feasible, even if the patient doesn t specifically have low serotonin levels. I would rather switch back to the Citalopram, than to continue to take Carbamazepine. I don t feel comfortable with long-term use of a seizure-control medication. Thank you, doctor.
