Focus Blocks

I would like to think I have a natural ability for this because it really doesn't seem that hard and I can get pretty close without following a formal technique, but I always have these problems that I will now list.

• For some reason I generate an excessive amount of saliva in my mouth and it always seems to bother me and I have to swallow only to notice right after I do that it produces more.

• I usually (almost always) feel what I think is sinuses on the back of my throa and I usually try to gulp it down because it is hard to ignore, but just like my above problem it doesn't take long to come back, sometimes it withholds for a little bit though  tongue.

Not that long of a list but these always tend to bother me greatly, can someone please help.

Also, this is not a problem but more of just a question for informational purpose. When ever I try to project and I get to a certain point where I no longer feel my body, maybe some slight buzzing or tingling, it feels like someone is holding my hand. Is someone other than myself trying to guide me through?
