Tami,

I increased my meds from 10mg to 20mg to 30mg and then to 40mg 4 wks. ago and I really didn't think it was working because I didn't feel any better by increasing to 40.  But by the end of the 4th wk. I did notice some slight improvements.  Each dosage gave me some improvements but not what I needed.  It takes time to find the right dosage.  So it does take time.  Do you not notice any difference or are you having side effects from increasing it?  Either case talk to your dr.  I see mine next wk.and I let him know eveything.  He usually tells me to give any changes to my meds. 4 wks. before we consider increasing, but that is how my dr. works.  So I may even increase again if we both feel it would give me more relief.  This is just my personal experience with meds.
