Hello Thank You for contacting HCM. Welcome to Health Care Magic. My name is Dr Muhammad Ahmad & i will look into your problem. I have gone through your query and would try to help you in the best possible way. THYROID HORMONE+CORTICOLE = Keep fuelling you body with instant energy. Cortisol is released when our body is in stress...or you can say when we need energy a boom our body secretes it,when do you need energy? to be euphoric,do fight, you be angry,to run... to feel joy...to enjoy every thing in life,for you body to function,rebuild recover from injury traums,to think fast to stay fresh ... and when body doesn t produce it you show signs opposite to what i just mentioned...so the absence of cortisol which was making you think slow feel lethargic ...made your brain on a dull side,made our body bwork below its potential...when it was given to you it has lit up every thing you metabolism,you brain,your feeling,your senses must have got sharper,your reflexes must have got quicker..and obviously your brain activity has increased... Increased brain activity = increased wakefulness = decreased sleep. Good new: Your body will soon get used to the normal levels of cortisol and your sleep will get to normal,THYROID HORMONE+CORTICOLE = Keep feuling you body with instant energy.Discuss with your doctor about your thyroid issues as well if its deraneged ....go through the process to maintain both thyroid and cortisol in normal range you will experience a new energy,a new world and a new YOU.
