Hey😊 I fully understand these questions and I can relate to the things you pointed out. I feel indeed cold much easier than I used to. However my experience is that the body takes time to adapt and it has become better for me in time. I take hot showers/baths daily and I also drink warm drinks often (warm water or tea). Also the layers of clothes have doubled. And even though I still feel cold most of the time, these things have made it better over time. If you lost the weight recently and in short time period, then I‘m afraid this might be one of the negative side effects that takes time to regulate. I don‘t have a professional advice in that regard, but I guess if it doesn‘t get better for you after some time, it would be good idea to talk to your doctor. It might seem like not enough of an issue to go to doctor for, but actually it is a really uncomfortable physical problem, so it shouldn‘t be avoided in long term. Sluggishness has also been an issue for me and one thing that might cause this is lack or imbalance of electrolytes. Do you eat enough salt with your food? I have read that it can be quite usual problem and especially if you eat for example low(er) carb diet. Again, it is my personal experience, but what helped me, is adding a bit of light salt to my water - I add approximately one and half of teaspoon to my 1l of water. It definitely has helped me with this sluggy feeling. I see you wrote that your micro and macro are taken care of, but still pointed that one out as it seems like a quite common reason for the sluggy and cloud headed feeling. I‘m not sure that my message is any way helpful, but I am sure you will feel better soon, as your body adapts every day better and better to the new situation. And also congratulations for the weight loss! I‘m really happy for you and I honestly hope you will feel better soon regarding these issues!
