I've been getting such bad headaches... Soooooo bad I can't deal with them...

I get them usualy within my first few sets of my first exercise then the rest of the workout day is ruined plus the rest of my day... I think it's from elevated blood pressure from test-e 500mg/wk... I'm thinking of cutting my cycle short and just saving what I have left for another cycle unless their was a way to get my blood pressure down to normal levels... Otherwise I will have to stop as I have never had this bad of a headache ever b4 in my life...
