I just took this med along with minocycline to treat a staff infection...after about 7 days I started noticing my tongue was very sensitive...like I ate too much hot spicy stuff and my taste buds were sticking up. Also got really itchy skin and not sure if this was because of this but my appetite changed dramatically...I was ravenously hungry every few hours...would actually wake up in the middle of the night and eat whole meals and then got horrible sleep to boot! I have been off of the meds for a day and a half and am starting to see my symptoms subside, but not completely. Was very irritable, tired, hungry and got very bad sleep while taking this. Not excited about ever taking it again, as I think it really messed me up!
