Question about my first 2 days taking this

Hey everybody, I’m just finding out about this wonderful substance and it came just in time. I picked up a 7oh addiction a couple months ago and I’m already miserable. Messed up digestion, no bowel movement,etc etc. so I ordered SR and it came yesterday. I’ve been taking about 30mg 3x daily while trying to drop 7 dose.

Every time I take the SR I get tired about 30 minutes after, not like a nod or a high. Like fatigue almost like a precipitated withdrawal. Has anyone heard of this? I know my dose is small is that potentially the cause? I was taking about 200mg of 7 and 50mg of pseudo a day roughly.
