I was on them for about 3 weeks. Started with 40mg a day for 7 days, then went to a 80 mg dose pack (3 days at 80mg, 3 days at 60mg, 3 days, at 40mg, 3 days at 20 mg). I did have some of the nasty side effect while taking them. Insomnia, stomach issues, acne, heart pounding, general feeling of anxiousness, feeling jitteryn all of the time. I do wonder if those symptoms didn't send me into a pattern (pyschologically) that I can't break out of. The lump in my throat feeling is gone today, and yesterday I had barely any muslce soreness. We will see what today brings, but I feel ok so far. I still had muscle twitches last night for about an hour and a half, but then they went away.
