Hello, Has anyone tried the Yasko BeCalm spray? I tried it two nights ago.. first night was interesting, I was tired within a hour.. I slept well initially then woke up a couple of times with heart beat slightly fast.. however went back to sleep easily (this is unusual for me). Second night, I took a little more (directions are 6 sprays, I took 2 the first night and 4 the second night). This knocked me for a six.. flat out asleep instantly, however woke coughing and heart racing. obviously I do not need much of this stuff. I did find something interesting though, I have had upper back pain ( since the I was pregnant) 12 years ago! I have tried everything, chiro, massage bla bla.. for the first time I have had no back pain in these 12 years.. Can Gaba do this? I am really quite ignorant of what Gaba does.. Yasko has suggested I take it ( genetic profile). d. Would anyone like to comment on this? cheers..
