Here is a simple and inexpensive idea, an oldie, but still a goodie. I found a decent inexpensive cologne (I found a large bottle at Walmart in a spray). After emptying, using a coffee stir (wood like from Starbucks for longer, the shorter plastic is fine also), tear a square of toilet tissue in half, spray it once or twice, fold it, insert it into pouch and push it up inside with the stick, then seal. Works 100% of the time and is inexpensive.
Parthenon sells a great tablet you chew or swallow and in conjunction with the above will reduce worries.
