What can I do for my allergy-induced insomnia while waiting for immunization?

[AndrewGreig]

I have allergies to so many environmental things like dust, mold pollen, dust mites etc., and no matter how much I clean or where I try to sleep at my home or even if I get hypoallergenic sheets my nose gets stuffed and I'll have poor sleep quality. I have not have a good night's sleep in over a month. I'm developing severe depression because I'm regularly sleep deprived. I went to an Ear Nose and Throat doctor and received nasal steroids but they don't help (so far, been using for two weeks). I am receiving allergy immunization treatment but that won't start to help me until 8 months. Antihistamines don't help all that well and they exacerbate my depression. I'm beginning to doubt that this problem is just an allergy problem. What can I do to help my insomnia while waiting? Do I need to see a sleep specialist?

Be sure to get the depression treated, as that may also fix your sleep issues.

Until the meds kick in then you have to try to deal with this as calmly as possible at bedtime, because frustration keeps your system from going to sleep. Try reading some books on sleeping issues, because they have methods to calm down although being stuffed up is a tough one to relax through.
Depression is a complex issue especially when you have a chronic medical issue, so how have you figured out that the depression is due to antihistamines?
