Allergic Rhinitis
"I can&#039;t understand how I have woken every night for the last 4 nights 
At around 3-4am and cannot get back to sleep again!!!  it has been driving me mad !!! 
Then when I put 2 &amp; 2 together I realised I started  montelukast 4 nights ago! Also have very swollen ankles and huge appetite! 
Not taking the medication tonight  as not worth it unfortunately"
