Neurontin and low sex drive

i have had a stroke in apr 2005 due to a random blood clot that traveled to the right side of my brain. the nerosurgeon prescribed neuronton and vicodin as my pain and nerve stimulant after we left the hospital. I have taken Neuronton 400mg 4 times a day and Vicodin750mg 6 times a day for pain. Also Zoloft and Zanax as needed . I have been taking this dose for 8 months. I now have a clot that is unopperable. My side effects are memory loss, pain in the rear of my neck,SEVERE pain in my thighs at night when I sleep, low sex drive,I cannot stay focused,vision problems,tired and weak, left arm is very weak. I am also experiencing kidney area pain now. Blood in stool is also concerning. I'm wondering if anyone with a stroke have near same symptoms. Also has anyone heard of this medication mixture?. I feel great soon after my dose is given but feel like i'm dying one hour before my next dose.

I started dating a guy that takes neurontin, thus the reason I am researching this drug. He is taking it for mood swings and a.d.d. He doesn't take it constitently. He takes various doses depending on the circumstances (sometimes he takes it like a party drug and he drinks). I can tell right away when he has taken a higher dose. He is lethargic, he drools, he is off balance, and actually seems somewhat slow (mildly retarded). I know he is intellegent, however, this drug is making him into a person that he should not want to be. I don't know if I can continue a relationship with someone that seems to be drugging himself to a complete stupor.
He said he was going to cut down to one pill, three times a day, however, I think he is having a very difficult time doing that. He is very addicted to his MEDS as he calls them. This drug seems to be destroying his life and he doesn't even know it.
He continually has to urinate, has a low sex drive and he experiences stomach problems along with back problems. This is the only drug that he takes. After what I have seen I wouldn't prescribe this to my worst enemy.
