I tried my Resperate for the first time yesterday and loved it! It was so relaxing that I used it again at night and had a great night sleep. Today, after I used it I did feel a bit light headed, is that normal? Also, I just started on BP medication and would love to be able to eliminate it at some point; my BP seems to be lower already, coincidence perhaps! At what point is my BP considered too low (with medication) that I should go see my doctor to make an adjustment in the dosage?
