I Have A Dry Mouth Syndrom , According To ANA

I have a Dry mouth Syndrom , according to ANA test and other rheumatological tests I am ok and hopefully no Sjoergen Syndrom . Sometimes I find it hard to swallow . All my throat stories came up after 2 antibiotics last November . Since last De 2015 I have this Dry mouth sydnrom now ,very strong, very disturbing .May it be related to a Gastritis ? I tried Symbioflor , Bioflor as Probiotics . About Gastritis I can't take Prevacid as a Protone Pump Inhibitor as I am allergic to Penicillin .So how to do , I stopped drinking alcohol . I drank but just 2 Glass of wine a night or 2 beers . Chinese Doctors say that I have a Heat between my lung and my heart . It feels like I am always dehydrated but I checked my Tyroid ,ok , diabetes 110 (5.8) ok , Hormones ok . Medication : no anticholineric drougs , only Candesartan 16mg twice (not HCT ) , 1 Zopiclon at Night (unfortunately for 3 years due to Insomnia for many years )

a)How to get Gastritis under control ?
b) Dry Mouth?
