What Causes Dry Mouth While On Gabapentin And Seroquel XR?

Question: I went through alcohol and xanax tetox in March 2016. I had a strong reaction to the phenobarbital. I also reacted to Seroquil and Gabapentin, and ended up going back in the rehab hospital 3 more times, due to inability to sleep. They gave me lithium and a low dose of Klonapin. I never did sleep and I still don't sleep much. Maybe 2-3 hours every night, never reach REM sleep.My symptoms are continual, loud ringing in both ears -t sounds like thousands of crickets are chirping in my ears. I also have completely lost my senses of smell and taste - and I have lost the ability to cry or "feel." My body feels very different to me, as if it is foreign. My skin feels dry to the touch. I do not feel at all like I used to feel. I also have a hard time being still. When I was in the hospital for the last time, in XXXXXXX 2016, I could not sit down at all. I paced through the halls of the hospital. Nothing ever helped me sleep while there. I have a dry mouth, and there is no taste in my mouth at all. The ear ringing is horrible. I feel as if my body is very anxious, but I can no longer "feel" the coinciding emotions. I have been reading about Conversion Disorder and I wonder if I have that. I was sexually abused as a young child and have gotten help for that. I also suffer from Dissociation -- I can remember nothing about my second grade year, and I remember very little about 2014 and 2015. My husband and I moved after living in our home for 23 years. I have had problems ever since the move, and he and I are having problems.
I have also read about Tardive Dyskinesia and I wonder if I have that, since it eppears my current symptoms were caused by hospital medications.
I have an appt with my psychiatrist in 2 weeks but I do not feel I can wait that long. It is very hard for me to function physically and emotionally and I rarely get out of the house.
I can tell that my body is anxious -my teeth chatter and I shake sometimes - but I cannot "feel." It is strange not to be able to smell, taste, or feel emotion. I used to be highly productive but now I get very little accomplished. Since we moved to anew house, I have lost contact with my psychiatrist and I have not received help from him since 2015. I did see several doctors while in the hospital last year, but I did not feel comfortable in that environment, or with those doctors. My reactions to Gabapentin andnSeroquil (and other drugs they gave me) were severe - visual hallucinations, jerking in my body, and a complete inability to sleep. It seems my health deteriorates every day - it is such an effort to even type tyis - it takes my complete concentration..
Do you have any idea what these symptoms mean? Thanks for your help.I am new to this site and I am not familiar with the format yet. Can you see previous questions I have asked? I hope so. Again, I am very concerned about the symptoms I am having. Thanks.

Thanks for your answer. I am very shaky and it has been a year since I went through detox.

Also, have you ever heard of someone losing their senses of smell and taste? And the constand ringing in my ears? Have you heard of this? Thanks.You responded to my questions about

alcohol and Xanax detox and tardive diskinosis. It has been a year since I went through detox - should I still be having withdrawal symptoms?

Also, why hav I lost my senses of taste and smell? Do you think they will return? And why cant I cry anymore? Is it the PTSD? I am going to have to get some relief for my anxiety.When I went through detox I had a strong reaction to Phenobarbitol, Seriquil. and Gabapentin, plus another drug given to help me sleep, but made me jerk. My body fills stiff and it is hard for me to function overall. I still cannot sleep well at all - 2-3 hours per night and no REM sleep. Thanks for your help. I have an apt with my psychiatrist in 2 weeks but I do not think I can wait that long.
