Saliva production symptoms and conditions

I have been taking Adderall xr for a while now. and every time either run out of it or don't take it for a few days, and then start up, the end of my tongue gets very red, raw, and sore, my throat is also sore and has a burning feeling to it. Is this related and if it is would Ritalin be a better choice.

Day 6 after laying down after taking doxy. Difficult to swallow , eat or drink. Headache gone, but burning in throat intense. Feels like labor pains in the chest. Lots of saliva production in the mouth. Seeing GI Dr tomorrow. !st 2 Dr.s think its the doxy
