Anyone know the bioavailabilities of doxylamine? Specifically... orally, rectally, intranasally, etc. I am having terrible insomnia and do not want to insuffilate anything and am hoping plugging doxy will achieve a similarly high BA as intranasal does.
From what I've heard on here... oral is around 20-25% and nasal is around 70% i'd assume plugging would be even higher...maybe 80-90%? anyone know and is there any safety issues with plugging a low dose (< 5mg) of this antihistamine?
Is it possible to make a solution of h2o and doxy and use it intranasally as a liquid to avoid any potential damage to the nasal lining and lungs from insuffilating powders?
