I have been taking Singulair for about a month now and feel that I have improved. There again, I have been up and down before so I can't be absolutely sure it will continue and in fact, it is due to Singulair. (As soon as I say I am feeling really well, I take a down turn - it's as though someone is saying don't get too cocky!) I don't want to jinx myself but we are supposed to exist on the least amount of medication possible so I was wondering if there is anyone out there who has improved on Singulair to the extent that they have been able to reduce say the seretide or stop the uniphyllin? If I continue to feel well (touch wood) of course I will ask my GP and will definitely will not do anything without his instructions but am just curious.
