(Very) Delayed Reaction??

I have been on Zep since Oct ‘24. Eight weeks on 2.5; eight weeks on 5; and 5 weeks on 7.5. Had some moderate GI issues when starting and titrating up. Those symptoms generally appeared on the day or 2 after my shot. Shots are on Tuesday mornings. Last Tuesday I took my fifth 7.5 shot. I have problems with constipation (even before Zep). Last Tuesday I was feeling the need to purge as I had been several days without. I took Miralax. Felt fine Tuesday and Wednesday but Thursday- oh my gosh!!!!! I was awakened with stomach cramping, severe gas and a need to go immediately. I’ll spare the gory details but let’s just say the evacuation was pure liquid for three incidents in a 45 minute span. The cramping dissipated and I ran some errands. My stomach continued to feel uncomfortable throughout the day. By dinner it was very uncomfortable. I ate what I could handle and went to bed early because I was really starting to hurt again. Horrible gas (sulphur burbs - which I had never had before), cramping and 3 more diarrhea events. Woke me up again at 2:00 and 4:00 with same episodes. Repeat at 7:00 AM. Extremely fatigued all day Friday (spent most of day in bed). No further issues until late evening when cramping and gas pains returned. Three more episodes in the middle of the night and again at 7:00 AM. None thru the day on Saturday. None on Sunday until late evening. So here we are on Monday (yep, 3 instances this morning) this stuff is still going on. Felt a little better through the day today. No more since this morning but stomach has been “gurgly”. I’m probably going to hold off on my shot that I was supposed to take tomorrow. I see my doctor on Wednesday. So, finally getting to my question (if you’re still reading, thanks!): has anyone else had this type of reaction? Again, this was my 5th dose of 7.5. TIA
