i was diagnosed with what the Drs said as a sluggish thyroid---i have had panic attacks for over 20yrs and just thought I was pooped from them---Dr gave me 25 levothyroxine and told me to give it aprox 3months---i did and well I felt terrible nervous, depressed and more panicky---i believe the depression was from feeling more panicky and not being able to socialize---so, my Dr took me off the 25 T4 and put me on DHEA and progesterone, after doing the saliva test to check certain levels. Her hopes are that I will get energy levels back without nervousness since she has noticed my hormone levels are off and as she said I have adrenal exhaustion. So, Im only on the 3rd day off of the T4 and on the current regiment of 25mg DHEA/B supplements/ EFAs/and Lyrica(25mg)/ and I have no energy at all-----i just want to sleep but i push myself but cant wait to hit the bed almost always right now--I never had these symptoms b4 I went on the T4 aprox 3months ago but now that Im going off I feel terrible, I am definitely calmer and less anxious now that I am off them but I cant make a decision to save my life and Im pooped!!! Does anyone know if going off 25 T4 could have such a drastic affect----thx so much-----
