if you have a chance to leave the country you can get these pills for a tenth of what it is costing you in other countries without a perscription! Such as Mexico, Thailand....etc I work overseas and was SHOCKED when I went to the pharmacy to get a weeks worth and wasnt asked for a perscription and only paid $3.50! To say the least I bought over 6 months supply and have never had a problem bringing it back to the states (although I check some and put some in my carry on)
