Why doesn't Amisan work?

Good morning thank you for your reply. As for your question, "Has the current inaction been communicated to the doctor?" So I informed the doctor, in March last year, that I do not feel the effect of the drug, my mood plummeted sharply, for which situations at work. Increasing the dose did not help. "Did the doctor recommend rescue use?" We came to the conclusion that we would increase from 150 to 700. But taking the drug in an increased dose, did not give any improvement. I decided from a conversation with the doctor that if it does not work, I will get off it completely. ". The patient's condition does not improve after taking a single or several tablets, and the resolution of acute symptoms of the disease or the relapse prevention effect is the result of several days or weeks of gradual development of the effect of the drug." Yes I know, I took the drug about 6 years on one fixed dose of 150. The drug is so good for me that immediately, the mood changed by 180 degrees, a plus. Most of the drugs I took didn't help me like he did, and there were a lot of them. Thank you very much for your reply Regards B.
