Look at your description, the question is very detailed. The current physical condition is mainly related to unhealthy lifestyle. As you can see from your cold drink, there is a serious accumulation of damp heat and cold in your body. The cold of cold drinks directly enters the pulse through the stomach, leading to cold accumulation in the uterus and dysmenorrhea; Its damp-heat spreads through the spleen and lungs, causing phlegm-dampness in the body and leading to disharmony between pulses. After stopping eating a lot of cold drinks, the above situation will gradually improve, but the cold accumulated in the uterus is difficult to heal itself.

The treatment is mainly spleen and stomach, which can strengthen spleen and stomach, replenish qi and blood, and warm meridians. It can be treated with Bazhen and Erchen plus rice kernel, Radix Cyathulae and Folium Artemisiae Argyi.

Besides, don't care about losing weight. When the physical condition is adjusted, it will be normal.
