I own AEZS too.. but have only been in it for a year.. together with KERX I have 11K shares. Not a lot but enough if they both go. Admittedly, this is an all in for me in the speculative part of my investments. I have bought and sold throughout the years.. still remember when it his a dollar and I thought I had hit it big... And then when it hit 6 ... that was some fun. Bought back in when it dropped and am in for the long hold now. Either way, I made my money a long tome ago..
