Replying to Supplements..halp.

I've been going to the gym for about 8-9 months i don't really remember my memory is quite blurry. i started out at 149 lbs now i am at 162lbs from excessivly working out and experimenting with different types of protein.
about 3 months ago i bought BSN's N.O Xplode. (yeah, yeah BSN is a rip off, some would say) it's been increasing my pumps incredibly and i notice my strength is increasing.
Today after coming back from working out, i did not take Xplode and i haven't been taking my Pro Weigh for about 3 weeks, i feel like shit, i'm all sore and cannot lift my normal weights, bench, curl, back ect. i have also not been following the cycle that N.O Xplode reccomends, after 12 weeks of use discontinue for 4 weeks. could this be the problem? not taking my whey protein consistently? has my body relyed on N.O soo much that i can't experience the fullest potential while i'm not on it?
And, it doesn't help that i'm on accutane,i'm taking it because i break out in the winter.
Also, my main strength is curling, i come back pissed like a bitch because of shooting pains from the side of wrists to elbow. Are there any wrist excersises you know of?
