so how many carts did you need for the 4/4 or 3/3 a day? i figure 3 carts would do for 6 weeks at 7 a day 4/3??? i got one cart left and just ordered two more with my dogs flea and heartguard stuff. i can always return them if i wuss out due to major anxiety and paranoia as well as sleeplesness by week 6 or oral fina. got xanax now that i hope will help, plus i'll keep the duration down to 6 weeks and lower dosage than last time (i think i did 9 or 10 a day).
