Troubles Deflating the Titan

[Alabama2015]

I am 2 weeks post op and was instructed to deflate the Titan one touch. I have easily found the deflate buttons and have squeezed them mightily. But I do not seem to be getting the deflation. I was inflated about 30%, so maybe I have succeeded but not noticed the difference. Has anyone else had this problem? After one gets used to this inflate/deflate process does it get pretty easy. In feeling the inflate bulb without trying to use it, it feels really hard and like it will be difficult to squeeze. I consider myself fairly strong so that should not be a problem.
