I thought I was crazy, it is still coming out of my system so maybe I am! I took singulair for 7 years, after doctors told me that Theo-dur was too old school. I have gained over 50 pounds, bad skin, bruising,diziness,insomnia and horrible temper and panic. Every time the Dr asks me how its going with singulair I say its fine.I think I put 2 and 2 together. After waking up with palpitations,shaking and generally freaking out I have decided to stop.I think it is still lingering in my body and I really hope this week I will feel better and not so tired.
