I cant do 40 mg. And especially just doubling it like that. I have to work my way up to 30 by alternating 20 and 30 days for at least a few weeks. Is this a male pdoc? Grrr. The kind that made all us women havd yearlh mammograms and now they say, oh doesnt make a difference?? Like to put THEIR bits in a vise. Sorry to rant. Yes i think its possible. My head feels cold at 40 mg. Its weird. Do you have 10 mg caps or can you split the pills? If its a 40 mg capsule you can dissolve it in half a cup of water and only drink part and save the rest, thats what my pdoc told me.
