hello!! fellow HH sufferers, im new to the site as far as posting but ive been reading on here for a long time. I have extremely severe HH, ive had it all my life. It was extremely bad for underarms and hands while growing up and i ended up having ETS in 2002. well,,,, my hands are better but not 100 % , of course the rest of my body is a mess!!! i travel often and spend time in tropical places sometimes for work and im completely drenched to the point where i cant function at all.... so ive been on robinul with mixed results,, it only works sometimes as u all know. it was almost completely useless for me in southeast asia. im considering working there but the sweat is the only thing holding me back. sweat has ruined my life. im in usa again now and i have a doctor apointment next week and i REEEEAAAALLLY want to request this diltiazem??? it is giving me hope!!! so im just posting here to say ill be experimenting with it hopefully?? if the dr agrees. and so i wanna post results here as well and encourage others to try too. congratulations cm123 on your success so far! sounds great! youve encouraged me to try it. ill try anything at this point. im just curious what you discussed about blood pressure though with your doctor?? as this med is for people with high bp? mine is slightly high anyway so im not worried but im wondering about dosage and the type to request? there seems to be many types, extended release etc...etc.. thank you all so much , lets all figure this out and make it work.
