Amien symptoms and conditions

I have been taken ambien for aprox five years, now due to back problems I also wear a fentanyl patch, at bedtime I take the ambien and heart medicine, if I stay in bed I am ok, but If I have to get up to use the bathroom its all over, my husband keeps an eye on me and I get goofy, write on nothing, talk to people he never heard of. although its been less, I am still doing it the next am my husband asks me if I remember and I do not, I do go to the refrig and eat ice cream but thats it. I ALSO now am on lyrica for back pain and I believe the two are not intermingling ok, as soon as I started the lyrica I started to gain weight, all my life my highest weight has been 145 last pm I weighed in at 166.8 pounds, something has to give, I cant breath good so don't walk much, its your damed if you do and damed if you don't!
