text: i am taking 'levothyroxine sodium ph. eur.' for an underactive thyroid. experiences/advantages/disadvantages? has anyone taken this or knows anybody who has? any experiences or advantages/disadvantages that you know of from taking this? does anyone know of any alternative therapies/treatment/foods that i can have instead? i take it for my thyroid also. i have pcos (polycystic ovarian syndrom) which has a lot of different symptoms, hypothyroidism is one of the symptoms. i have a book about pcos that states that healthy diet and exercise along with weight loss can help control just about everything. in fact most people that change their lifestyle with better eating and exercising can go off of almost any medication. it lowers your blood pressure, makes your body absorb insulin better so a lot of diabetics are able to go off or decrease their meds, people with heart disease improve their chances of not having heart attacks with just 30 minutes of walking a day. i am on the journey to get off my meds. i take levothyroxine, hydrochlorothiazide and birth control (to regulate my periods mostly). it may take a while, but it will work! i feel pretty good on the drug. no side effects i can tell. good luck!
