Pmt/periods - help

I rarely post here but just found this thread. I started Sinemet a year ago alongside the mini-pill and have just come off the mini-pill as I put on 2 stone since starting it. Before taking both of those meds I was completely knocked out for about 3 weeks a month - for a week before, a week during and a week after my period. I've been off the pill for a month and am feeling worse than I have for a year. I don't really like being on the pill but if the alternative is feeling like this (I am not prepared to up my Sinemet as I'm only 45) I think I might have to go back on the pill. Has anyone found anything at all that helps deal with the sledgehammer of symptoms that occur around their period?
