Welcome to HCM
Its good that you have reduced most of your medicines. I advise you to stop all medicines if you were taking them without consultation of doctor. Medicines for sleep are mostly addictive so they should be used only on prescription. As you are still having the problem of insomnia and you are planning to conceive so visit to a Psychiatrist
is really needed. He can evaluate your problem and will advise medicines if needed.
Medicine like Ramelteon
are non addicting and are very useful. Even in initial results ramelteon is thought to be safe in pregnancy.
Improving sleep hygiene
is also must to improve sleep.
Fix your time to go to sleep.
and yoga will help to improve.
Use bed only for sleeping and not for watching TV or reading books.
Avoid tea/coffee/carbonated drinks in evening
Warm water bath is evening will also help
Try not to think about again and again because it will only increase anxiety and will ultimately worsen sleep.
So good luck and visit a psychiatrist for opinion.
