Same with me; I can go out the morning after my shot and do shopping etc. I have shots Wednesday nights; Thursday okay, Friday I'm pretty heavy, Saturday spacey and Sunday starting to normalise.
My nurse suggested I worked 3 days a week at least; I'm glad I didn't, I wouldn't have got the days right :-). I read somewhere that Peg peaks over a 3-4 day period (don't quote me, but it makes sense).
Sandbash - headaches? Are you drinking enough water? Are you getting anemic? Take care - I hope this week's better for you.
About the same for me....but last week headaches lasted all week. It seems to be a lot better if I stay busy (even if its just watching tv or reading) rather than try to sleep it off.
