going from 12.5 ambien cr to 6.25 ambien cr

[stable not balanced]

hello! i would love to hear from you. so, here goes:

one reason for the switch is to possible help my short-term memory.

also, maybe not so tired the next day.

also, less meds.

what i would like to know is, does one feel withdrawals?

should i kinda taper off by alternating the two doses?

did i hear that they are made of different ingredients?

if so, what physical difference does this make?

thank you!
