I have been on Armour for 12 months now and am now on 2.5 grains per day and was exercising 5 times a week in 45 minute classes the week before last. I gave up smoking last Monday and by Friday all my hypo symptoms were back and I can now hardly get out of bed. My pulse last night and this morning 56 whereas last few months about 70. BP 123/76 sitting standing 135/84. I know from reading the archives that quite a few people are diagnosed with thyroid issues after giving up. I know I will have to go for a blood test but that will take a week or so. What have others done in the meantime who have recovered, did you have to up your medication after stopping? Did your bloods show TSH raised and T3 lowered after giving up?
