Someone really close to me has severe anxiety and OCD. She takes medication for it and her medication became unbalance because of something else she took. She stared acting really odd. A few days later she told me that she doubled her medication and now felt normal whereas before she told me that she felt crazy. I'm not sure if she had the okay from her doctor to up her dose or she just did it on her own. Can this level someone out in a few days or would it make it worse?
