I find it helpful to switch around my daily allergy meds every once in a while. Allegra is really good for me for at least a couple of week. I'm on levocetirizine right now (Xyzal). I would recommend them both.

What was the use case for the Wickford Junction line? It can't be that they expected people to travel to Wickford Junction on the train, because there's so little within walking distance to make it useful. Were they hoping people who worked in South County would commute to the station, park there, and take the T to their jobs in Providence, or Boston? I doubt there are many commuters in South County who work in Boston, due to the 2+ hour commute each way. I also doubt there are many people who work in Providence who would take the rail, because public transportation in Providence is awful. Unless you work right by the station, you are looking at a commute of the same exact amount of time if not longer by taking the train. If you have a connecting bus, since there's no subway in Providence, you're looking at an hour+ commute instead of 30 - 45 minutes. This ignores whatever your commute time from your home to Wickford Junction is. The population around there is not dense enough to support the rail line or to allow residents to live without owning a car.
