Hi, Thanks For The Rapid Response! Okay So I Have

Hi, thanks for the rapid response! Okay so I have a few questions....Does crystal meth thin your blood? Also, my friend has seriously swollen feet and legs...to the point where i am concerned and afraid of a blood clot or congestive heart failure working on him. He is swamped in work and insistent on waiting until tomorrow to go the the hospital and I can't seem to change his mind. Is there anything you can recommend for him to do in the meantime? I have instructed him to drink water, elevate his feet, and drink alcohol (as an attempt to keep his blood somewhat thin; just in case his blood is coagulating in there).
