Hashi symptoms and conditions

I have Hashi's and have been on Synthroid for about 2 years. I was recently on 75 mcg and was teetering on the brink of being hypo again so my doctor increased my dosage to 88 mcg last week. Ever since I have been on the new dosage, I have had the worst insomnia. I wake up covered in sweat (in air conditioning) and I feel caffeinated all the time ( I don't consume caffeine). I feel strung out! Is my body just getting used to the new dosage or am I being over medicated? I don't want to complain yet to my doctor if this is just my body getting used to the new dosage but this really is terrible.

I am a diabetic with hashi. I had been taking synthroid longer than metformin and had been on both for at least a year now. Recently I have been to ER due to heart palpitation and shortness of breath, so I had stopped my synthroid .1 for one day and felt better. So I stopped taking synthroid altogether, After 3 weeks I took it again because I was afraid not to follow my doctors order. 3 days into it, I was back to a high pulse, shortness of breath, chest pin and palpitation. I went to a different doctor,
and he agreed that we experiment on the dosage and try a generic brand.
I took .25 this time and I had the same reaction as taking synthroid .1.
I have now stopped completely, I am hoping to that my doctor will listen to me and will give something else other than synthroid.

My daughter (now 18) was diagnosed with Hashi's 2 1/2 years ago. She had headaches, was tired more than usual and irregular periods. Now on synthroid for 2 1/2 years, she has steadily gained over 35 lbs. She works out every day and eats ONE meal per day. Doesn't matter. Doctors all lie about this side affect. Her weight gain has made her borderline type 2 diabetes now. (she's about 170).

Is there anyone who's been through this and has a reasonable approach?
