Did not suit me.
on 25 May 2015
I bought this hoping it would help me sleep. I think it had some effect (getting to sleep may have been easier) but it was not right for me.
Firstly, when I took it I think it gave me vivid/unpleasant dreams. This may be something to do with increasing the amount of REM sleep (I don't really understand these things); however, this might be beneficial to others. Secondly, I think it has a diuretic effect because when I took it I had to get up in the night. So, on the whole for me the negative effects outweighed the positive effects.
I have not tried other brands so can't say if any of this is true for any other L-Theanine supplier. If you feel inclined to try this don't be put off by my experiences - we are all different and others seem to do well with this stuff.
