Synthroid and weight watchers

Hello Ladies....I am 56 and diaged Hashimotos disease 3 years ago.At the moment on 112mcg of synthroid....dosage started off low and have gradually worked up....So angry with drs...was seeing endo, but moved and using family practice...so frustrated with weight gain approx 25lbs since diag. Also does the word sweat ....mmmm perspire for all us ladies, mean anything? I can't even wash dishes without breaking out in to a sweat...mmm beads of perspiration....Dry skin, I own stock in Aveeno....Also....does anyone get "boil type" skin eruptions in the nether region...butt, inner thighs etc? Does anyone or has anyone done any serious research on Iodine? I try to eat as well as I can, was doing Weight Watchers and gained weight do ya hear me? I am questioning my idodine intake or lack of....Presently take mulit vit with 150mcg. Considering uping it and dc ing my synthroid...cuz docs have been useless....eat less, (how much more less?) exercise more...I swim so much I look like a freaking prune....Any comments?

i've been on synthroid for 9 years. started at some low dose and gradually went up to112 mg. get extreme itching all day everyday if i don't take allegra for that.not a rash just itching. that doesn't bother me as much as the fatique. every joint in my body aches all the time. sure there are better days but fo rthe most part it's bad. tried physical therapy and chiripratic care but no avail. they ended my sessions. my legs get sooo weak and my feet burn lower back really aches. sometimes muscle cramps. i'm very negative towards my loving family and it hurts me to do so. can't seem to keep upbeat. soo tired all the time.
is it the syntroid? i used to be very energenic and a doer. now i have spurts of activity in the morning , but then i just can't get motivated. help me any suggestions?
