Talk to your doc about bumping to 5mg. 2.5mg feels light if you were taking 7.5mg before. When you stop tirz it washes out in the first month but your system stays a touch desensitized. Folks often need higher doses after stopping. Stay at 2.5mg and it builds with each shot for the initial four doses. At shot four you'll have roughly 4mg in your system versus almost 12mg when you quit at 7.5mg. Hang in there and update us.
