How much pseudoephedrine can I get until they start thinking I'm a smerf?

I have had an ear infection since about August (2013). In late November I went to the Texas Med Clinic and they prescribed some antibiotics and suggested pseudoephedrine. Basically I got a 20 pack of 12-hour pills (pure pseudoephedrine) at the beginning of November. I then got two more doses (same pack) in December.

Then, when in January I got a horrible earache, I went to an ENT and he said I should take Claritin-D (loratadine and pseudoephedrine). Basically I've been on this since January. In two follow ups, the ENT prescribed more Claritin-D.

So basically, since November, I have gotten four 20 packs of 12-hour pure pseudoephedrine and just recently got a 10 pack of 24-hour Claritin-D (generic) and will have to get another one, a 6th one, to make it to my next doctor's appointment (he said to keep taking it until my next appointment) by February 27th.

So that's 6 things of pseudoephedrine in three months. Am I going to get in trouble for getting this much pseudoephedrine or is this dose considered "normal" for medicinal purposes?
