i'm impressed by this site, i've been on Armour 2 1/2 gr. for 1 month now and am experianceing some shortness of breath--have to stop to get my breath frequently with any excertion...In 2 more weeks, i am to get my blood work done again...highest TSH was 61 -4 wks after TT-then i month on synthroid 150 and came down to TSH of 18, so was upped to synthroid 175 for a month and came down to 6--was then switched to Armour and i am finally not feeling so HYPO (when you call it hypo he//, I AGREE) after viewing this site, i stopped taking my Armour, all in one dose, by swollowing it first thing in the morning (5 am) and started to divide it into 2 doses and letting it melt under my tongue, and have only been doing this x 1 wk. I am finding that i have a little more energy in the afternoon, now-but by 8:30 pm--the party is over and i am dragging, but since i get up at 4:45am i am ok with that...only symptom i am having is S.O.B. with excertion--no chest pains-neck/jaw/arm pain--had some heart palpations the 1st wk, but not now--i'm so afraid of the Dr. lowering the dose, when i am starting to feel a little more umph.. i started all of this in Aug/08 'cause of hyperparathyroid-then a lump on my thyroid-CA-which involved 3 lymph nodes also--RAI of 150meq and am so ready to have my life back...I had a friend ask me when my TSH was 6- whats wrong with you- your verily out of the normal range...i really appreciate the support i have felt by just reading this site- thanks for all the good posts and you guys seem very knowledgable by your experiances.
