Ive been taking the 0.5 alprazolam round peach with the R and 029 on other side. Recently I was switched to the 0.5mg alprazolam oval peach with GG 257. I know they are the same thing but it feels like the oval ones don't kick in as fast and sometimes last longer. What's up with that? Has anyone else noticed a difference between the two? I thought maybe the coating is thicker so I tried sucking on them a bit before I swallow (yummy) but it didn't change anything. Any information on this would be good because I feel the need to redose and thats not right.
