Tamsulosin
"i was prescribed this crap almost 18 months ago and it has nearly killed me. Bad sleep to start with,tired all the time, dizzy, hard to breath and I couldn't do anything without gasping . I stopped this 3 days ago and its a friggin miracle. I feel great I can  breath, can walk with gasping  and had a good  sleep last night. Well yes it could  be something else.  ---I have been to cardiologist --gastroenterogist-- and 3 more and they didn't see the relationship. Crap even had a angiogram after 2 STENTS that were done. Last angio said no need for stent and after that still felt terrible with symptoms above. I stopped tamsulosin and feel great. What a friggin joke medicine"
