Hey Heather!
it is nice to meet you! I'm kind of in the middle of dealing with all this Hurricane Rita stuff down here in Louisiana, but I noticed your post and wanted to encourage you to read the info I posted under the "Depression Articles" posted here under the "Depression and Weight Issues", especially the 3rd page at:
http://www.3fatchicks.com/forum/show...6&page=3&pp=15
where I shared info about the connection between bipolar and thyroid problems.
If you are like me (and many others) you have been told many times over the years that your "thyroid is normal" but unfortunately, most docs are simply running the TSH which can easily miss the problem. The need to run the Free T3, Free T4 and antibodies tests, which are much more accurate. All of the info is there in those threads, but I just wanted to encourage you to at least thoroughly check out your thyroid and make sure it is not causing the problem.
I cannot tell you how many stories I have heard just like yours, and they ended up finding out they actually have a thyroid problem and do much better on a T3/T4 combination like Armour Thyroid.
I don't mean to butt into your business but wanted to at least share the info with you. Please let me know if I can help in anyway.
take care,
Cathy
