metformin for insulin resistance ? need help

[infinte_pain]

I am hypothyroid , with extreme fatigue and sleepiness i sleep for 15 hours a day , My thyroid function is perfect according to the blood results , i have been hypothyroid for 4 years . My fasting and post prandial blood sugar is normal , hb1ac 5.6 , howeever my  fasting insuling is bit elevated but post prandial insulin level is skyrocket  , it is 190 while top range for post prandial in the test is 20 . I feel extreme thirsty and sweat very much and urinate 4 times in the night . I read online that high insluin level in blood can cause fatigue and brainfogg just as i experience now , I had done all tests thats related to fatigue :- sleep analysis feritin , vitamin d , magnesium , electrolytes , cortisol etc .  so i want to try metformin to lower insulin . can anyone tell me how much time does it take for metformin to effect the insulin level  . and i dont see major sideeffect caused by metformin . what do u guys think . i  was overweight  , now i reduced my weight to the normal range with dieting and exercise still my insulin is high . every help will be hugely appreciated i am currently writing this with huge brainfogg and sleepiness . sorry if i made grammar mistakes

Hello,

you may want to go check out the thyroid forum on this site and see if your thyroid really is properly treated.    If your doctor only tests TSH, then you may not be ok.  You also need to have FT3 and FT4 tested and both should be at least middle of the range.    What thyroid meds are you taking?  

Metformin is a useful drug for reducing insulin resistance.  It is certainly rational for you to ask your Dr. to let you try it.

Suggest also low carb, moderate protein, high healthy fats diet.  it may help with your energy levels too.
