If our health felt normal whilst on thyroid gland hormone replacements, there would be no need as forums such as this as we would be busy getting on with our lives/families/work. There are now over 8,500 members!!!
If you are not well on levothyroxine, they can add some T3 to a reduced T4.
They should be able to prescribe T3 alone, any of the natural dessicated thyroid hormones and let the patient tell them when they feel well. If the patient took a bit too much, it is easy to address by either missing the next day's dose or reducing it.
These are some links which will give you information. We have to learn and read unfortunately in order to get better. Is there any other auto-immune disease that has the same problem?
Synthroid is the USA equivalent of levothyroxine.

There are two potential sources I know of for people feeling awful when they are on T4-replacement. One source is the extremely low dosage that doctors typically prescribe nowadays. A low dose of T4 can effectively reduce TSH secretion. The lower TSH can in turn lower the thyroid gland’s output of thyroid hormone. At the same time, low-dose T4 may not compensate for the thyroid gland’s reduced output of thyroid hormone. The patient then has too little thyroid hormone to properly regulate the metabolism of most of her body’s tissues. She then ends up with abnormally low metabolism and troubling hypothyroid symptoms. I’ve written about this before on drlowe.com.
The second possible reason for your bad reaction to Synthroid is that T4-replacement simply won’t work for you. It doesn’t work for many hypothyroid patients. In a recent study in the United Kingdom, for example, T4-replacement left 50% of patient suffering from hypothyroid symptoms (Saravanan, P., Chau, W.F., Roberts, N., et al.: Psychological well-being in patients on ‘adequate doses of L-thyroxine: results of a large, controlled community-based questionnaire study. Clin. Endocrinol. (Oxf.), 57(5):577-585, 2002.) Unfortunately, through faulty reasoning, these researchers concluded that a much smaller percentage of patients suffered from symptoms despite being on T4-replacement. They are mistaken about the percentage. The evidence is overwhelming that T4-replacement is the lousiest approach to thyroid hormone therapy. I’ve documented the widespread failures of the approach in two critiques:
An extract from Dr S
A World Thyroid Register has been formed to address the parlous situation of patients who are hypothyroid and have yet not been diagnosed and indeed patients who are being managed with an unacceptably low level of thyroid replacement. The situation has significantly worsened in the last one year pursuant to pronouncements in the United Kingdom from the Royal College of Physicians and the Royal College of General Practitioners who inter alia have suggested that patients should not be diagnosed with hypothyroidism if the TSH is <10.0 and moreover that Armour Thyroid is a 'bad' preparation because the proportions of T4/T3 may not reflect the human proportions while contemporaneously suggesting prescription of T4 alone; this makes no sense at all.
