Hi I Have Had Hypothyroidism For 10 Years. I Take

Hi I have had hypothyroidism for 10 years. I take levothyroxin which keeps my levels at a low minimum. Since having the disease I have never resumed my pre-condition state of feeling energetic. I suffer terribly from insomnia and always struggling to maintain my weight. I was considering taking adding Actalin to my regiment in hopes of increased energy. Or is this not a good combination?
