Brief Answer:
Underlying causes should be ruled out- further explanations on possible conditions and stepwise approach below

Detailed Answer:
Hello and welcome to "Ask a Doctor" service,

I carefully read your query and understand your concern.

Increased saliva is called hypersalivation and can be caused by a large number of conditions such as stomach acid reflux (GERD), oral cavities and other mouth and throat conditions, neurological diseases, toxins (mercury, arsenic, copper, etc), side effects of medications (Zoloft is often thought to cause dry mouth so it is less likely to be the cause of your symptoms), etc.

You will need to have a thorough check with your doctor to rule out problems with mouth, teeth, gums and also have a neurological examination to make sure there are no such underlying conditions.
If all the examinations are normal then you may try treatment for GERD for a while (omeprazole 40 mg 30 minutes before breakfast to reduce the stomach acid and its reflux in the throat).

If this is not helping enough, other treatments to reduce saliva include:
- brushing your teeth and using mouth wash (these may cause dry mouth)
- avoiding food that may cause increased production of salivae such as lemon (citric fruit) and strong taste or spicy food
- medications such as Glycopyrrolate tablets 1 mg 3 times a day are found effective in reducing the amount of saliva produced
- intraoral tropicamide films may provide temporary relief
- if the above measures do not help well enough then more permanent treatments such as botulinum toxin injections, surgery or radiation (this one is very rarely used) can be used depending on the patient.

To conclude:
- you will need to have a good visit with your doctor and probably with your dentist as well to rule out oral cavity problems and other medical conditions that may cause your symptoms.
- avoiding food that makes you worse is necessary and brushing your teeth regularly and use of mouthwashes has a good effect in drying the mouth
- if no physical factor is identified then antireflux drugs (Omeprazole can be tried)
- other medications that are used to reduce the amount of saliva are Glicopyrrolate oral tablets and tropicamide oral films- these may have side effects that cause patients to drop the treatment.
- other more invasive measures can be tried in severe cases that are not affected by the above measures (botulinum injections, surgery and very rarely radiotherapy).

I hope this answers your query. I remain at your disposal in case further medical assistance is needed.
