So I'm writing this out seeking others like me. Back beginning in February I lost 40 lbs over a span of 5 weeks. I thought I was doing the right thing. Didn't realize losing that much that fast had side effects. Beginning around April I began having muscle twitching, usually mild. I haven't lost strength but my muscles are smaller. I also have strange sensations now like leg tingling, vibrations like feelings anxiety. I had blood work done in May and it came back low testosterone low vitamin d and low end b12 readings. I guess I'm just wondering if there's anyone out there experiencing what I'm going through or if someone has an idea how to stop this .
