I have been taking levoxyl for 13 years. I have experienced a lot of the symptons you describe. It took almost 5 years to find the right dosage that I feel normal on. Just because the TSH is in the normal range doesn't mean you'll feel normal. I went to a specialist who tweaked the doses till I felt my best. For me that is a TSH of between 1 and 2. If it goes lower or higher, even though it is in normal range I get symptons of either hypo or hyperthyroidism. Each time a dose is ajusted it takes a good 3 to 4 months for your body to adjust. So finding the right dose is a long process. And finding the right Doctor to work with you can be a long process. The Doctor told me the thyroid is the theromstate of your body and if it isn't set exactly right you'll feel it. It regulates everything. I have never had an allergic reaction side effect of levoxyl just dose related side effects and they can be very depressing. To give all of you hope I can say that once you find your dose you'll feel like your old self again.I feel better then ever.
