I was diagnosed as hypo last year. The very few symptoms I have, I've had for 40 years. I feel extremely well without medication. The only symptoms I have (as far as I'm aware) are, feeling the cold (not as bad as I used to), never feeling refreshed when I wake up, even if I've had a good night's sleep. That's it as far as I'm aware. I did take the lowest dose of levo for 3 months but was reluctant to carry on as it didn't make any difference. I realise I may have needed a higher dose before noticing any difference but as I don't feel ill I was worried that I may have adverse side effects; as some people do; until I got the correct dose and once I'd, possibly, had adverse effects it may take a long time to get my body back on track.
