Struggling

I am 8 days post treatment, I had 30 days radiotherapy and 2 sessions of Chemotherapy.  I am struggling with recovery.  Excess saliva is the main thing, I am sat all day and night with a bowl constantly spitting into it. It really getting me down is there anything I can do . I was told this was normal after treatment but doesn't feel like. I am feeling so down
