Hi, In recent months my physical activity very much limited, gained some weight. Wearing of mask continuously and continuous sitting abstracting my breathing capacity.  I am experiencing the symptoms like giddiness, headache, sweating, high blood pressure, increased heart rate and breathless ness. And sleeplessness during nights due to suddenly getting a wake due to lack of oxygen supply. May be suspecting sleep apnea. I started doing physical activity 20 min morning and evening. But nights my sleep not yet improved. Due to lack of sleep may be my immunity levels may go down and I may be vulnerable to Covid repository issues. Please provide urgent medication for this situation. Thank you.
