Biaxin and shakes

Being a registered nurse, I know that all medications have potential for side effects. And with this type of forum, it is important to know that people who do not have side effects often don't write in BLOGS so there is a very biased view of the totallity of effects. Having said that, I've been on Biaxin XL for 4 days. This medication has really messed with my stomach since day 1. Starting day 2 was the night sweats and vivid nightmares. Nighmares puts it lightly- it was more like night panic. Day 3 started with diarrhea. So now I'm at day 4 with all my sweat, shakes, nausea, cramps, diarrhea and I can't wait to go to bed to have more nightmares. What can happen to me next?

i have severe shakes and covered in hives and yes they itch.

body can't tolerate BIAXIN. due to time release of pill, bitterness remains in mouth 24hrs. bitterness keeps me awake at night. nightmares, leg cramps. tongue slightly swollen. taste is overwhelmed by the bitterness i can't get rid of. constant nausea. am drinking water literally every minute to keep sickening taste in mouth from making sick to stomach. have shakes. side effects are too distracting to take further after 2 days. this should be taken off the market.

third day of Biaxin XL....
