I do take a little every morning. Probably wishful thinking, but I'm hoping it acts an antidote to the diphenhydramine I use as a sleep aid.
I know many people have trouble sleeping, but I highly suggest trying to find something else to help you sleep. Many natural supplements and herbs aid in sleep, e.g. valerian, theanine, melatonin (don't exceed 3mg - more than that can cause extremely vivid, active, dreams), GABA, ashwagandha, and others.
My fiance uses a product called Dream Water and it really helps her sleep (she suffers from PTSD).
Antihistamines like Benadryl (diphenhydramine) block histamine (obviously). The problem with that, besides drying out your eyes, nasal passages, throat, etc., the chronic use of histamine blockers can result in hypertension.
Histamine is a vasodilator, which is why when someone goes into anaphylaxis, their throat swells shut, their hands and limbs swell, their face swells.
When a person who is so allergic to a substance they go into anaphylaxis, their body produces overwhelming amounts of histamine, which dilates the blood vessels, including the capillaries, and you get massive swelling in the throat, the extremities, etc. Depending on the histamine release, pulmonary edema can result as well. Epinephrine (Epi-Pen) counters anaphylaxis because epinepherine is the most potent vasoconstrictor. It's also why after using an Epi-Pen, you must get to the hospital. The effects of the Epi-Pen will not last as long as the allergen in your body.
Conversely, by constantly inhibiting normal levels of histamine, that natural vasodilation is blocked, and contributes to hypertension.
Be aware that medications such as Pepcid and Zantac are also histamine blockers. We routinely prescribe such drugs when treating an allergic reaction.
