Up to 50mg for supraventricular tachycardia. Also clinically depressed and extremely stressed. Now having more depression, anxiety, mood changes, fatigue but insomnia at night, Also, gross diarrhea and increased ringing in my ears. Somehow, I think it may be better to have the ablation procedure, which I am told can totally fix my electrical rhythms in my heart. Am thinking of it as I already have struggles with diarrhea from ahivng Crohns disease and having a few feet of large intestine removed. Also, lack of appetite, not increase.
