My brother has been dealing with depression for 4 years. Ever since Covid. He has lost 75lbs. Says food doesn’t taste right We have him drinking shakes and we prepare food for him that he likes. He’s very picky because of the taste of foods. He’s confused and can’t focus. He had brain scans. Found nothing. Also has had etc and magnetic therapy. Nothing helping. Very sad situation. He’s been in hospital 2xs and sees a psych. He’s still trying different meds. Nothing seems to work. Looking into spravado a form of ketamine you sniff up the nose. Don’t think he’s a candidate. Any thoughts are appreciated.
